A single "turn" of the Krebs cycle will yield 1 ATP, 3 NADH, and 1 FADH2.

A single "turn" of the Krebs cycle, also known as the citric acid cycle or the tricarboxylic acid cycle, involves a series of chemical reactions that occur in the mitochondria of cells. These reactions lead to the production of ATP and electron carriers such as NADH and FADH2, which are vital for cellular energy production through oxidative phosphorylation.

During one complete cycle of the Krebs cycle, which starts with the entry of acetyl-CoA, the following compounds are generated:

3 NADH: The Krebs cycle generates three molecules of NADH. NADH is a high-energy electron carrier that carries electrons to the electron transport chain (ETC) in the mitochondria. NADH is later oxidized in the ETC, leading to the production of ATP through oxidative phosphorylation.

1 FADH2: The Krebs cycle produces one molecule of FADH2. Similar to NADH, FADH2 is an electron carrier that transfers electrons to the ETC. FADH2 provides electrons at a later stage in the ETC compared to NADH, resulting in a slightly lower yield of ATP.

1 ATP: Through substrate-level phosphorylation, one molecule of ATP is directly synthesized during the Krebs cycle. This ATP is generated by the transfer of a high-energy phosphate group to ADP from a phosphorylated intermediate molecule.

Based on the above information, the correct answer is: 1 ATP, 3 NADH, and 1 FADH2. This reflects the ATP directly produced during the Krebs cycle and the electron carriers NADH and FADH2 that are generated and subsequently participate in the ETC, leading to the production of additional ATP molecules through oxidative phosphorylation.

Organisms that reproduce by cloning have no way to affect the future of their genes.

Cloning is a type of asexual reproduction where the offspring produced is genetically identical to its parent. In this process, a single organism gives rise to a new one without the involvement of gametes or fertilization. This type of reproduction, however, means that any genetic mutations or changes in the parent's DNA will be replicated in the offspring without the possibility of variation.

These organisms do not have the genetic diversity needed to adapt to changing environmental conditions, making them more vulnerable to environmental threats that could threaten their survival. In contrast, sexually reproducing organisms produce offspring with unique genetic characteristics that increase their chances of survival in a changing environment. Therefore, cloning does not allow for genetic diversity and adaptation that are required for survival in the future.

The antibiotic that disrupts cytoplasmic membrane function is amphotericin B.

antibiotics are medications used to treat bacterial infections. They target specific components or processes within bacterial cells to inhibit their growth and reproduction. One such target is the cytoplasmic membrane, which surrounds the bacterial cell and regulates the movement of substances in and out of the cell.

Out of the given options, the antibiotic that disrupts cytoplasmic membrane function is amphotericin B. Amphotericin B is a polyene antifungal antibiotic that is also effective against certain bacteria. It works by binding to the sterols in the cytoplasmic membrane, causing the membrane to become permeable and leading to cell death.

The antibiotic that disrupts cytoplasmic membrane function among the options provided is E) amphotericin B.

Amphotericin B is an antifungal antibiotic that disrupts cytoplasmic membrane function in cells. It binds to the fungal cell membrane, specifically targeting ergosterol, a key component of fungal cell membranes, and forming pores. These pores disrupt the integrity of the membrane, leading to leakage of cellular components and ultimately causing cell death.

Although the other antibiotics listed in the options (streptomycin, erythromycin, tetracycline, and penicillin) have various mechanisms of action, they do not directly target or disrupt the cytoplasmic membrane function.Therefore option E is the correct option.

Amphotericin B is particularly effective against fungal infections but can also have toxic effects on mammalian cells due to its nonspecific nature. Therefore, it is mainly used in severe or systemic fungal infections where other treatment options are limited.

1. c. Haplotype Recombinant.

2. c. trisomy 21 > Robertsonian translocation > PKU syndrome.

1. The term that does not involve multiple loci is c. Haplotype Recombinant. Haplotype refers to a set of genetic variations on a single chromosome, while recombinant refers to the reshuffling of genetic material during meiosis. It does not inherently involve multiple loci, but rather the arrangement of alleles at a single locus.

2. The correct order of DNA alterations, in large to small scales, that cause the phenotypes mentioned is c. trisomy 21 > Robertsonian translocation > PKU syndrome. Trisomy 21 refers to the presence of an extra copy of chromosome 21, resulting in Down syndrome, which is a large-scale alteration involving a whole chromosome. Robertsonian translocation involves the fusion of two acrocentric chromosomes, often resulting in rearrangements and genetic disorders. Phenylketonuria (PKU) syndrome, on the other hand, is caused by alterations in a single gene, resulting in the inability to metabolize phenylalanine. Therefore, the order from large-scale to small-scale DNA alterations is trisomy 21, Robertsonian translocation, and PKU syndrome.
