1a. What are the main products of TCA cycle?

ATP/NADH

NADH/Suagr

NADH/O2

CO2/O2

1b. The respiratory quotient for lipid is less than 1 that means...

Iipid has less energy

lipid has more energy

lipid uses more energy to process

lipid has same amount of energy as sugar

Solution

1a.Answer is option a.

NADH is the product of TCA cycle but sugar is not the product of TCA cycle.

So,option a is not correct.

Oxygen is also not the product of TCA cycle.

So, option b is not correct.

CO2 is the product but O2 is not the product of TCA cycle.

So,option d is not correct.

ATP/NADH are the product of TCA cycle.

Hence,option a is correct.

1b.Answer is option c.

Lipid has more and less energy is not the correct option.

So,option a,b are not correct.

Lipid has same amount of energy as sugar,it is also not correct.

So,option d is also not correct.

Lipid uses more energy to process than other materials.

Hence,option c is correct.
