Explanation / Answer

Q.1) In Eukaryotic cells, Glycolysis occurs in the __________, Pyruvate Oxidation and the Citric Acid Cycle occur in the ________, and the electron transport chain is in the _____________.

Answer: d) Cytoplasm; Mitochondrial matrix; Mitochrondrial inner membrane.

Glycolysis occur in cytoplasm in which glucose will be converted to two molecules of pyruvate

Citric acid cycle occurs in mitochondria matrix.

Electron transport chain occurs in cristae of inner matochondria membrane.

Q.2) We can detect tyrosinase among thousands of other proteins in a mushroom extract (in a solution or in-gel) because:

Answer: a) Its bigger than other proteins

Tyrosinase is bigger than this cutoff, it will not pass through the filter.

Q.3) The highest energy carrier (transfer molecule) in cells is:

Answer: c) ATP

ATP is the most widely distributed high-energy compound within the human body.

The remaing molecules (acetyl-coA) are considered as electron carriers though they release ATPs in electron transport chain. But immediate energy carrier molecule is ATP.
