The citric acid is a stage of catabolism that oxidizes acetate into carbon dioxide and generates energy. There are eight enzymes

3241004551 [841]

Answer:

1.(a ) alpha-ketoglutarate dehydrogenase

(c) malate dehydrogenase

(d) isocitrate dehydrogenase

2. b. isocitrate dehydrogenase d. alpha-ketoglutarate dehydrogenase

3. b. citrate synthase (c) succinyl-CoA synthesase

4. b. alpha-ketoglutarate dehydrogenase c. citrate synthase d. malate dehydrogenase

5. a. aconitase

Explanation:

The citric acid cycle is responsible for the oxidation of acetyl-CoA produced from pyruvate from glycolysis. The citric acid cycle has eight steps requiring nine enzymatic reactions involving eight enzymes.

The enzymes in the citric acid cycle are: citrate synthase , aconitase, isocitrate dehydrogenase, alpha-ketoglutarate dehydrogenase , succinyl-CoA synthesase, succinate dehydrogenase , fumarase , and malate dehydrogenase .

1. The dehydrogenation reactions of isocitrate dehydrogenase, alpha-ketoglutarate dehydrogenase , and malate dehydrogenase produces NADH from isocitrate, alpha-ketoglutarate and malate respectively.

2. Oxidative decorboxylation (removal of carbon as CO₂) also occurs in the reactions of isocitrate dehydrogenase and alpha-ketoglutarate dehydrogenase to produce alpha-ketoglutarate and succinyl-CoA respectively.

3. Coenzyme-A (CoA-SH) is produced in the reactions of citrate synthase and succinyl-CoA sythetase to produce citrate and succinate respectively.

4. The enzymes alpha-ketoglutarate dehydrogenase has alpha-ketoglutarate as substrate , whereas citrate synthase and malate dehydrogenase has oxaloacetate as substrate. These substrates are alpha-keto acids.

5. Aconitase catalyzes the conversion of citrate to isocitrate by first a dehydration and then a hydration reaction.

Many of the responses to stress are attributed to activation of the sympathetic nervous system and are mediated by

belka [17]

Answer:

Responses to stress are attributed to activation of the sympathetic nervous system and are mediated by adrenal medulla which is the central portion of the adrenal gland.

Explanation:

Stress is a physical, mental, and emotional response to a threat, and causes bodily and mental tension. There are different causes of stress, for example, an exam, a divorce, moving from a house, being fired, somebody’s death.

The body’s stress response is mediated by the sympathetic nervous system (SNS), and the hypothalamic-pituitary-adrenal (HPA) system. The SNS is responsible for the neural fight-or-flight response to stress.

In a stressful situation the hypothalamus, which is in charge of the stress response, sends signals to the pituitary gland and the adrenal medulla. The adrenal medulla secretes the neurotransmitters and hormones adrenaline and noradrenalin to the bloodstream. These hormones get the body ready for a response to stress, by increasing heart biting frequency and strength, increasing blood pressure, stimulating respiration, and dilating respiratory tracts.

Once the threat factor is over, the body gets back into a balanced state.

Two brown-eyed parents have a baby with blue eyes. Explain how this could happen?

tigry1 [53]

Answer: They must be Carriers Bb of the bb genotype.

Explanation: Blue eyes are a reccessive phenotype meaning its visable. If both parents are carriers of this gene Bb and they reproduce their is a 25% chance the baby will have blue eyes, a 50% chance they will be carriers like their parents, Bb, and a 25% to be completely dominant brown eye geneotype, BB.
