The complete oxidation of alanine produces 7 CO2 molecules and generates 16 ATP. NADH and FADH2 yield 10 and 6 ATP respectively.

Alanine is an amino acid that is a major source of energy for the body. During cellular respiration, alanine undergoes a series of reactions that release energy and produce ATP (adenosine triphosphate). The complete oxidation of alanine generates 7 molecules of CO2 and 16 ATP.

The reactions involved in alanine oxidation occur in the citric acid cycle (also known as the Krebs cycle or TCA cycle) and the electron transport chain (ETC). In the citric acid cycle, alanine is first converted to pyruvate, which is then converted to acetyl-CoA and enters the citric acid cycle. This process generates 1 NADH, 1 FADH2, and 2 ATP per acetyl-CoA molecule.

The NADH and FADH2 generated in the citric acid cycle are used to generate ATP in the ETC. NADH and FADH2 are electron carriers and are used to transport electrons from the citric acid cycle to the ETC, where they are used to generate ATP. NADH yields 3 ATP and FADH2 yields 2 ATP.

Therefore, the net production of NADH and FADH2 in the complete oxidation of alanine is 10 ATP and 6 ATP respectively. The total ATP production from the complete oxidation of alanine is 16 ATP.

Biological treatments of hazardous waste involve using plants, bacteria, or fungi to absorb and detoxify hazardous substances. The correct option is D.

Biological treatments of hazardous waste involve the use of living organisms, such as plants, bacteria, or fungi, to absorb and detoxify hazardous substances. This approach is known as bioremediation and is aimed at reducing or eliminating the harmful effects of hazardous waste on the environment.

In bioremediation, specific plants, bacteria, or fungi are selected for their ability to metabolize or break down the hazardous substances present in the waste. These organisms can absorb or take up the contaminants from the soil, water, or air, and through various biochemical processes, transform them into less toxic or non-toxic forms. This helps in the natural degradation and removal of hazardous substances from the environment.

Plants used in bioremediation, known as phytoremediation, can uptake and store contaminants in their roots, stems, leaves, or other plant parts. Bacteria and fungi, on the other hand, can directly degrade or transform the hazardous substances through enzymatic reactions.

Biological treatments offer several advantages, including their potential for low-cost and environmentally friendly solutions. They can be used to remediate contaminated soil, water bodies, or air, and have been applied in various industrial and environmental cleanup scenarios.

It's important to note that the specific approach and choice of organisms for bioremediation depend on the nature of the hazardous waste and the environmental conditions present at the site.

Answer:

Explanation:

Checkpoints play an important role in the onset of cancer. They are regulatory mechanisms within cells that help ensure proper progression through the cell cycle and prevent the formation of cancerous cells. The checkpoints are responsible for monitoring cell growth and division and ensuring that DNA damage is repaired before the cell continues to divide. If these checkpoints fail, the cell can continue to divide with mutations and other genetic abnormalities that can eventually lead to cancer.

There are two main checkpoints in the cell cycle: the G1 checkpoint and the G2 checkpoint. The G1 checkpoint determines if a cell is ready to enter the next phase of the cell cycle, while the G2 checkpoint monitors DNA damage and checks for errors before the cell can undergo mitosis. If either checkpoint fails, the cell may proceed with division despite having genetic mutations that can increase the risk of cancer.

In addition to these checkpoints, there is also a third checkpoint, the M checkpoint, which monitors the progress of chromosomes during cell division to ensure that each daughter cell receives an accurate copy of the chromosomes. If the M checkpoint fails, it can result in the formation of aneuploid cells, which are cells with an abnormal number of chromosomes. Aneuploidy is a hallmark of cancer and is associated with a high risk of developing malignant tumors.

In conclusion, the role of checkpoints in the onset of cancer is critical as they help prevent the formation of cancerous cells by monitoring cell growth, division, and DNA damage. The failure of checkpoints can lead to the formation of mutated cells that are more likely to develop into cancer.

Explanation:

An endangered species is one with a reduced population. These species can easily become extinct if all the remaining members die.

The term used for the high-energy species that is formed along the pathway of the enzyme-catalyzed conversion of substrate to product is the transition state.

The transition state is a fleeting, unstable and high-energy configuration that the substrate molecule must pass through in order to be converted to the product. The activation energy required to reach the transition state is provided by the enzyme, which lowers the energy barrier and facilitates the reaction. The formation of the transition state is a critical step in enzyme catalysis, as it determines the rate and specificity of the reaction. Enzymes bind to the substrate and stabilize the transition state, thereby increasing the rate of the reaction.

If negative selection of T-lymphocytes in the thymus never occurred, it would likely result in the presence of self-reactive T-cells in the immune system.

Negative selection is a process that occurs in the thymus, where T-lymphocytes (also known as T-cells) are exposed to self-antigens. This process helps to eliminate T-cells that recognize and react to self-antigens, which could potentially cause autoimmune diseases or inappropriate immune responses.
If negative selection did not occur, self-reactive T-cells would not be eliminated and would be released into the bloodstream. This could lead to an increased risk of developing autoimmune diseases, where the immune system mistakenly attacks healthy cells and tissues in the body.
In summary, the absence of negative selection in the thymus would likely result in the presence of self-reactive T-cells, increasing the risk of autoimmune diseases.

The unusual nature of viruses, behaving as living organisms while within them but becoming inert while isolated, has led scientists to consider the possibility that viruses may exist in a gray area between living and non-living entities.

Viruses possess genetic material, replicate, and evolve like living organisms, but they lack the ability to metabolize and carry out other life processes independently. This unique behavior has prompted researchers to classify viruses as "obligate intracellular parasites" that rely on host cells for their replication.

While viruses are not technically alive, they have significant impacts on living organisms, causing diseases and driving evolution. In summary, viruses challenge our understanding of what constitutes life due to their dual nature and reliance on host cells for survival and reproduction.

Septic shock due to gram-positive bacteria is caused by the release of bacterial exotoxins. These exotoxins induce the production of proinflammatory cytokines, resulting in excessive vasodilation, hypotension, and ultimately, septic shock.

Septic shock is a life-threatening condition that is the result of an overwhelming immune response to an infection. Gram-positive bacteria, such as Staphylococcus aureus and Streptococcus pyogenes, are a common cause of septic shock.The bacteria release exotoxins, such as superantigens and lipoteichoic acid, which stimulate the immune system to produce large amounts of proinflammatory cytokines. These cytokines then cause excessive vasodilation and capillary leak, leading to hypotension, reduced perfusion to vital organs, and ultimately, septic shock.

Symptoms of septic shock include fever, low blood pressure, rapid heart rate, rapid breathing, and altered mental status. Treatment typically involves antibiotics to target the underlying infection, as well as fluid resuscitation and vasopressors to restore blood pressure. Early recognition and treatment of septic shock are critical for improving outcomes and reducing mortality.
