the condition marfan syndrome results from the production of abnormal elastin, the main component of elstic fibers. predict the

valina [46]

Protein elastin is used to made elastic fiber, component of connective tissue that found abundant in blood vessels, bones, tendon and skin. The effect should be prominent in those organs.

Aorta is the biggest artery blood vessels and it need more elasticity to withstand the pressure of the ventricle. Less elasticity makes aorta become enlarged. The bone will lose density and become thinner. The tendon in heart valve will be weaken and might cause the heart valve disease. The skin will lose elasticity, so it will be easier to stretch.

Which of these statements correctly compares probeware (such as an electronic temperature probe) to traditional analog tools (su

sattari [20]

These tools are used to measure or identify certain degree of occurrence depending on which specific area it is used. Thermometers are used to measure the degree of temperature in a room, area or a certain location. Moreover, probewares use electrons and the activity or heat signature in a room while liquid based uses the heat of an object to indicate how much heat energy is involved.

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.
