Question

beta oxidation is an example of

1, linear pathway

2, cyclical pathway

3, branched pathway

4, spiral pathway

for a biochemical reaction to be spontaneous, the free energy change should be

1, negative

2, positive

3, zero

4, at equilibrium

the product of anaerobic glycolysis in humans are

1, lactate and NADH

2, lactate and NAD+

3, ethanol and NADH

4, ethanol and NAD+

which of the statement of catabolism is false?

1, it produces ATP

2, it degrades larger biomolecules into smaller ones

3, intermediate can be channeled between different pathways

4, there is a net gain in NAD+

Answer 1

1. (4) spiral pathway- same set of enzymes operate in a repeated manner

2. (1) Negative

3. (2) lactate and NAD+

4. (4) There is net gain of NADH in catabolic pathways; produced from NAD+
