2026 COMPLETE QUESTIONS WITH
SOLUTIONS GRADED A+
◉ True or False: Enzymes are polysaccharides that catalyze chemical
reactions.
Answer: False
Enzymes are PROTEINS that catalyze chemical reactions
◉ What is a cofactor? And give a general example.
Answer: A cofactor is a small chemical component that assists an
enzyme during the catalysis reactions. A cofactor is usually metal
ions.
◉ Define anabolism.
Answer: Anabolism is the process of building up smaller molecular
units into larger complexes
◉ In order to convert proteins into amino acids which metabolic
process would be active?
, Answer: Catabolism would be active because proteins are made up
of amino acids. Therefore the process would be the breakdown (or
catabolism) of proteins into amino acids.
◉ Describe the energy transfer process relative to both ATP and
ADP.
Answer: ATP has the energy (phosphate group) to DONATE, while
ADP can ACCEPT energy from the form of a phosphate group.
Therefore, ATP can be reduced while ADP can be built up.
◉ From what source do chemotrophs acquire energy?
Answer: From preformed chemicals found in the environment
◉ An organism that derives its energy by removing electrons from
elemental sulfur would be classified as a __________?
Answer: Litotroph
◉ This phosphorylation process occurs in the mitochondria of
chemotropic eukaryotes.
Answer: oxidative phosphorylation
◉ The catabolism of a single molecule of glucose goes through what
3 distinct transitions?
Answer: 1. Glycolysis
