Which type of noncovalent interaction can incolce either the polypeptide backbone or amino acid side chains?

Answers

Answer 1

Hydrogen bonds are the type of noncovalent interaction that can involve either the polypeptide backbone or amino acid side chains.

Hydrogen bonds are the non-covalent interactions formed between two molecules. It is the bonds between an electropositive atom of one molecule and another electronegative atom of another molecules. Hydrogen atoms are formed between the atoms in covalent bonds. These atoms are found in polypeptide backbone as well as amino acid side chains.

Amino acids are the molecules that form the proteins. This happens by the joining of amino acids together by peptide bonds. There are 22 amino acids that are involved in the protein making process.

The glucose and ethanol similar in structure and function as the ethanol fermentation, also called alcoholic fermentation, is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as by-products.

What is the process obtaining ethanol?

Ethanol has been obtained from three important steps and these are mentioned below:

Measure a quantity of a solution of sodium dichromate acidified in a dilute sulphuric acid and pour into a test tube.

Add excess ethanol. This is because if we don't do so there will be plenty of oxidizing agent to carry out a second operation which changes the aldehyde to ethanoic acid. However, we need only the aldehyde

When the aldehyde ethanal begins to form which will be evident by the change in the colour of solution from orange to green, then the mixture should be distilled from the test tube and tbethe aldehyde collevted so that it doesn't undergo additional oxidation into ethanoic acid.

Therefore, the glucose and ethanol similar in structure and function as the ethanol fermentation, also called alcoholic fermentation, is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as by-products.

Answers

The nice assumption of the dominant and recessive phenotypes be long flagella is dominant, single vacuole is dominant.

A vacuole is a membrane-bound organelle found in the cells of plants, fungi, protists, and some animal cells. It is a large, fluid-filled sac that occupies a significant portion of the cell's volume. Vacuoles are involved in a wide range of cellular processes, including storage of nutrients, waste products, and pigments, as well as regulating turgor pressure and maintaining the pH balance of the cell.

In plant cells, vacuoles are particularly large and play an essential role in maintaining the plant's structure and function. They can also act as a defense mechanism by storing toxic compounds to deter herbivores or pathogens. In contrast, animal cells have smaller and fewer vacuoles, which are primarily used for storing nutrients or waste products.

Which of the following bone(s) would ossify via intramembranous ossification Group of answer choices Both the Rib and Skull Rib Femur Skull

Answers

Both the Rib and Skull bones ossify via intramembranous ossification.

Intramembranous ossification is one of the two primary processes by which bones are formed during embryonic development and bone growth. It involves the direct ossification of mesenchymal or connective tissue membranes without the presence of a cartilage precursor. This process is responsible for the formation of flat bones, such as the skull bones and ribs.

During intramembranous ossification, mesenchymal cells within the connective tissue membrane differentiate into osteoblasts, which are responsible for bone formation.

The osteoblasts secrete an extracellular matrix composed of collagen fibers and other substances, which then become mineralized to form bone tissue. This process occurs directly within the mesenchymal membrane, resulting in the formation of flat bones, such as the skull and ribs.

Therefore, both the rib and skull bones undergo intramembranous ossification, where bone tissue is formed directly from mesenchymal cells without the involvement of a cartilage template. This process contributes to the development and growth of these bones, providing them with strength, structure, and protection.

what is the fate of glucose 6-phosphate that enters the pentose phosphate pathway in the flight muscles of hummingbirds?

Answers

The right response is that ribose-5-phosphate and carbon dioxide are created from glucose-6-phosphate.

The glucose-6-phosphate is converted into ribose-5-phosphate, which is the five-carbon sugar molecule and carbon dioxide, after entering the pentose phosphate pathway. Following the entry into the route, glucose-6-phosphate is initially converted into 6-phosphogluconolactone by the enzyme glucose-6-phosphate dehydrogenase.

The generation of NADPH also occurs during the conversion of glucose-6-phosphate to the lactone molecule. By the action of the enzyme lactonase, 6-phosphogluconate is created from the 6-phosphogluconolactone that is generated. This is further decarboxylated and hydrolyzed into carbon dioxide and ribose-5-phosphate by the action of the enzyme 6-phosphogluconate dehydrogenase. The hummingbird's flight muscles convert glucose-6-phosphate in order to produce NADPH and protect against oxidative stress.

The complete question is:-

What is the fate of glucose 6-phosphate that enters the pentose phosphate pathway in the flight muscles of hummingbirds? Glucose 6-phosphate is converted to carbon dioxide and ribose 5-phosphate.

DNA and replication, explain why this is an effective strategy against the proliferation of cancer
cells. One of the side effects of chemotherapy is hair loss. Explain why this happens.

Answers

Cancer can be treated by using chemical analogs that stop the DNA replication process, whereas chemotherapy produces hair loss due to the elimination of rapidly growing cells.

What are chemical nucleotide analogs?

The chemical nucleotide analogs are molecules that mimic natural nucleotides in the DNA double helix such as Adenine, Guanine, Cytosine and Thymine; however, once included during DNA replication they can stop this process.

Chemotherapy can promote hair loss because these chemicals kill not only cancer cells but also rapidly growing cells such as hair follicle stem cells.

Answers

Answer:

the answer is B.

based on the graph, the higher the sugar concentration in the glucose solution, the more the potato strip loses mass. this is due to the net movement of water molecules out of the potato strip into the glucose solution of lower water potential. as such, the potato strip loses more mass if placed in a glucose solution of higher sugar concentration.

B is just the reverse: the lower the sugar concentration of the glucose solution, the more mass would be gained by the potato strip (due to the net movement of water molecules INTO the potato strip this time round)
