Lean body mass is the most important factor that increases Basal or resting metabolism.

Lean body mass plays a significant role in increasing basal or resting metabolism.

Basal metabolism refers to the energy expenditure required to maintain essential bodily functions while at rest.

It represents the minimum amount of energy needed to sustain vital processes such as breathing, circulation, and cell maintenance.

Lean body mass, also known as muscle mass, includes all the body's tissues except for fat. Muscle tissue is metabolically active and requires more energy compared to fat tissue.

Therefore, individuals with a higher proportion of lean body mass tend to have a higher basal metabolic rate (BMR) or resting metabolic rate (RMR). This means they burn more calories at rest, contributing to increased metabolism.

By increasing lean body mass through regular exercise, such as strength training, individuals can raise their basal or resting metabolism.

This can have benefits for weight management and overall energy expenditure. However, it's important to note that other factors, such as age, sex, and genetics, also influence metabolism.

Pip3 recruits Akt, a PH domain-containing protein, and PDK1 to the plasma membrane.

Phosphorylation of PIP2 to generate PIP3 is a critical step in the insulin receptor signal. PIP3 recruits various signaling molecules to the plasma membrane, which initiates downstream signaling events. One of these signaling molecules is Akt, a PH domain-containing protein, and PDK1, which activates Akt. This recruitment and activation of Akt leads to the activation of various signaling pathways that regulate glucose metabolism, cell growth, and survival.

PIP3 is an important signaling molecule that is generated by the phosphorylation of PIP2. PIP3 recruits various signaling molecules to the plasma membrane, which initiates downstream signaling events. One of the critical signaling molecules recruited by PIP3 is Akt, a PH domain-containing protein, and PDK1. Akt is a serine/threonine kinase that plays a critical role in regulating glucose metabolism, cell growth, and survival. Akt activation is necessary for the downstream signaling of the insulin receptor signal.

When PIP3 binds to Akt, it causes a conformational change that exposes the catalytic site of Akt. PDK1 also binds to the PH domain of Akt and phosphorylates Akt at threonine 308, which is necessary for Akt activation. Activated Akt then phosphorylates downstream targets, including glycogen synthase kinase 3 (GSK3), which regulates glucose metabolism, and mammalian target of rapamycin complex 1 (mTORC1), which regulates cell growth and protein synthesis.

In summary, phosphorylation of PIP2 to generate PIP3 propagates the insulin receptor signal by recruiting Akt and PDK1 to the plasma membrane, which activates Akt and initiates downstream signaling events. Akt activation plays a critical role in regulating glucose metabolism, cell growth, and survival.

: There's only one stable, long-lasting biosphere that we know of. It's the Earth. It shouldn't surprise you that human attempts to create sealed systems don't generally fare very well. The International Space Station, despite efforts to recycle everything possible (including converting urine to drinkable water--do you still want to be an astronaut?) to reduce costs, couldn't sustain life for long without a steady supply of provisions from, and garbage hauling back to, Earth. You know they try hard because, if all goes as planned, it costs about $10,000 to put a pound of payload (supplies) into Earth orbit. The BioSphere 2 project in Southern Arizona was an interesting and costly effort, but the original studies weren't very scientific and it proved quite difficult to keep just a handful of humans alive for a relatively short period of time. You can buy tiny sealed marine ecosystems enclosed in glass. They are beautiful curiosities, but the one I bought for my wife lasted less than a year before crashing. Among the crazier justifications for space exploration is that when (note the assumption of inevitability) we ruin the Earth, we will need new places to live (and, presumably, ruin). Unless or until we can do a lot better at building self-contained ecosystems, it would be a far better use of human effort to focus on preserving the only one we've got. Not only that but, if we make the Earth uninhabitable, I'm not sure we deserve to live somewhere else. But the challenge itself is interesting, and the scientific questions you can ask in the process of understanding, building, and trying to maintain such a system are valid. We're going to give it a try. Good luck! There's a Nobel Prize in it.

Rob who doesn't have ichthyosis will have the genotype 12 12.B. The given probabilities can be found by using the Punnett square method. Probability that Ana and Rob have a daughter who has patchy ichthyosis but not cystic fibrosis is 1/2.

Given data:

Ana's dad: TTAhna: T12Rob: 12 12

The allele for ichthyosis can be represented by T and for normal allele 12.

TT = IchthyosisT12 = Ichthyosis12 12 = Normal

Cystic fibrosis can be represented by F and the normal allele can be represented by f.

As given in the previous question, Ana is heterozygous for cystic fibrosis which means her genotype is Ff. Rob is not affected by cystic fibrosis, so his genotype is ff.

We can now create a Punnett square to determine the probability of Ana and Rob having a daughter with patchy ichthyosis and not cystic fibrosis.      f    fF    FFf    FfFf    Ff

When we take a look at the Punnett square, we can see that there are four possible outcomes for their children.

Answer:

The plasma membrane is a thin layer of lipid molecules that surrounds the cell and separates the inside from the outside. The fluid mosaic model describes the structure of the plasma membrane as a two-layered structure of phospholipids with embedded proteins. This model explains how the structure of the plasma membrane allows it to act as a selective barrier, regulating the movement of substances in and out of the cell.

Structure S in the plasma membrane is represented by the phospholipids, which form a lipid bilayer with hydrophilic heads facing outwards and hydrophobic tails facing inwards. The hydrophilic heads are in contact with the extracellular fluid and intracellular fluid while the hydrophobic tails are in the middle of the membrane. The phospholipid bilayer provides a barrier that separates the inside and outside of the cell, restricting the movement of hydrophilic and large molecules through the membrane while allowing the passage of small and hydrophobic molecules.

Structure T represents the integral membrane proteins that are embedded in the lipid bilayer. These proteins have different functions, such as transport of molecules, cell signaling, and catalyzing chemical reactions. The proteins also contribute to the selective permeability of the membrane by regulating the movement of specific molecules in and out of the cell. For example, channels and carrier proteins regulate the movement of ions and larger molecules through the membrane while receptor proteins receive signals from the outside of the cell and relay them to the inside of the cell.

In summary, the plasma membrane is mainly composed of phospholipids and proteins according to the fluid mosaic model. The phospholipids form a lipid bilayer that acts as a barrier, while the proteins embedded in the bilayer regulate the selective permeability of the membrane by facilitating the movement of specific molecules in and out of the cell.

The given statement, when the rate of alcohol consumption exceeds the liver's metabolic capacity, blood alcohol levels increase and symptoms of intoxication develop is True.

Because When the rate of alcohol consumption exceeds the liver's metabolic capacity, blood alcohol levels will increase and symptoms of intoxication will develop. This happens because the liver is not able to metabolize the alcohol as quickly as it is being consumed.

The result is that the alcohol will build up in the bloodstream, leading to an increase in blood alcohol levels and symptoms of intoxication. Common signs of intoxication include slurred speech, impaired coordination, slowed reaction time, and impaired decision-making. As blood alcohol levels increase, the effects of intoxication become more severe, including loss of consciousness and even death.

Cellular metabolism encompasses all the chemical reactions and processes that occur within cells to maintain life and support various physiological functions. These processes include the conversion of nutrients into energy, the synthesis of molecules needed for cellular structures and functions, and the elimination of waste products.

Cellular metabolism involves two main types of reactions: catabolism and anabolism. Catabolism refers to the breakdown of complex molecules into simpler ones, releasing energy in the process. Anabolism, on the other hand, involves the synthesis of complex molecules from simpler ones, requiring energy input.

These metabolic processes are tightly regulated and interconnected, involving various enzymatic reactions and molecular pathways. They play a crucial role in activities such as energy production, nutrient utilization, cell growth and repair, and the maintenance of homeostasis within the body.
