Explanation / Answer

Answer:

Q1.ans: The 3 steps involved in aerobic respiration are:

*The first step in is glycolysis,

*the second is the citric acid cycle and

*the third is the electron transport system.

Q2ans:An amphibolic pathway means containsboth catabolic and anabolic processes.

*The KREBS CYCLE or citric acid cycle is a series of reactions that degrades acetyl CoA to yield carbon dioxide, and energy

And that is used to produce NADH, H+ and FADH.

Q3.ans: Glycolysis in cytoplasm,

TCS in mitochondria.

Q5ans:. In TCA the products are

6 NADH molecules(6×3=18ATP),

two FADH2 molecules(2×2=4ATP),

and two ATP molecules.

So,totalATP=24.

Q6. Answer:3controling enzyme:

1.citrate synthase,

2.isocitrate dehydrogenase

3.-ketoglutarate dehydrogenase.

Q7ans:The glyoxylate cycle, it is a type ofvariation of the tricarboxylic acid cycle, is an anabolic pathway occurring in plants, bacteria, protists, and fungi.

**The glyoxylate cycle involves the conversion of acetyl-CoA to succinate for the synthesis of carbohydrates.

Q8answer:

Anaplerotic reactions ,are chemical reactions that form intermediates of a metabolic pathway.

Example: the citric acid cycle (TCA cycle).
