Direct use of oxygen is in:

In the ETS in mitochondria, identify the product that is not correctly matched with its number:

When the amount of ATP is increased in a cell, it is expected to:
1. inhibit the enzyme phosphofructokinase.
2. activate the enzyme citrate synthase.
3. inhibit the enzyme pyruvate kinase.
4. activate the enzyme pyruvate dehydrogenase.

Maximum energy can be released during the oxidation of:

The glycolytic pathway occurs in:
1. cytoplasm
2. chloroplasts
3. matrix of the mitochondrion
4. cristae of the mitochondrion

In lactate fermentation, the final electron acceptor is:

Brown fat tissue in vertebrate animals:
1.is the most common storage form of fat
2.allows the animals to regulate their metabolic rate when it is especially hot
3.promotes fluidity of the biological membranes
4. regulates temperature by converting energy from NADH oxidation to heat

Refer to the diagram given below:
 

Identify the incorrectly matched pair:

Beta oxidation in respiration is associated with:
1.oxidation of pyruvate
2.activation of acetyl CoA
3.electron transport chain
4. breakdown of fatty acids
