Glycolytic pathway evolved very early in evolution. This is supported by the fact that:

1.	The ATP production in glycolysis is much less than in oxidative phosphorylation.
2.	It is found in the cytosol, does not involve oxygen, and is present in most organisms.
3.	It is found in prokaryotic cells but not in eukaryotic cells.
4.	It does not need any enzymes that evolved much later.

Out of the following what is both used and produced during the glycolytic pathway?
I. ATP
II. ADP
III. Phosphate groups
IV. NADH
1. I, II and III only
2. I, II and IV only
3. I, III and IV only
4. I, II, III and IV

Which of the following is an allosteric enzyme?
1. Hexokinase.
2. G3P dehydrogenase.
3. Fumarase.
4. Phosphofructokinase.

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
