BIOD 171/ 171 PORTAGE LEARNING (2 VERSIONS) FINAL EXAM WITH VERIFIED QUESTIONS AND ANSWERS
VERSION 1
• Define catabolism.
It is a
... [Show More] process that allows larger molecules to be broken down into useful energy sources.
• Upon cellular injury, which metabolic process is involved during the growth and repair phases of the cell? The anabolic process because it is involved with building up small complexes into larger complexes.
• True or False: Metabolism is a controlled set of biochemical reactions that occur in living organisms in order to maintain life.
True.
• True or False: Enzymes are polysaccharides that catalyze chemical reactions. False. Enzymes are proteins that catalyze chemical reactions.
• What are usually metal ions known to assists enzyme during the catalysis reaction? Cofactors are usually metal ions and assist enzyme during the catalysis reaction.

Describe the energy transfer process relative to both ATP and ADP.
ATP gives energy whereas ADP accepts energy to become ATP. During the donation of energy, ATP transfers energy from the breakdown reactions which is used for building up. This fuels cells to carry out necessary biochemical reactions for survival.
From what source do chemotrophs acquire energy? From chemicals that already exist in the environment.
An organism that obtains its source of carbon from inorganic molecules such as carbon dioxide is referred to as a ?
autotrophs
This phosphorylation process occurs in the mitochondria of chemotropic eukaryotes.
A. Photophosphorylation
B. Substrate-level phosphorylation C.Oxidative phosphorylation
• Identify the products of the following chemical equation: Glucose + 2NAD+ → 2 NADH + 2 Pyruvate + 2 ATP
Glycolysis produces pyruvate molecules, NADH molecules and ATP.
• What are the main two roles of glucose-6-phosphate in the cell?
prevention of glucose from diffusing out of the cell
is the signal molecule to the cell that glycolysis is going to begin soon. [Show Less]
