question 1 (1 point)
which kind of metabolic poison would most directly interfere with glycolysis?
a chemical that reacts with oxygen and depletes its concentration in the cell
a chemical that binds to pyruvate and inactivates it
chemical that blocks the passage of electrons along the electron transport chain
a chemical that closely mimics the structure of glucose but is not metabolized.
question 2 (1 point)
in the electron transport chain, which of the following is the strongest reducing agent?
cytochrome c
o2
cytochrome oxidase
nadh dehydrogenase
question 3 (1 point)
what are the products of the atp hydrolysis reaction?
adenosine diphosphate, water, and free energy
adenine, an inorganic phosphate, and free energy
adenine, three equally bonded phosphates, and free energy
adenosine diphosphate, an inorganic phosphate, and free energy

Explanation:

Question 1: Glycolysis is the first - stage of glucose metabolism. A chemical that closely mimics the structure of glucose but is not metabolized would most directly interfere with glycolysis as it could compete for glycolytic enzymes.
Question 2: In the electron - transport chain, NADH Dehydrogenase is involved in the transfer of electrons from NADH. NADH is a strong reducing agent, and the enzyme associated with its oxidation is also related to reducing activity.
Question 3: The hydrolysis of ATP (adenosine triphosphate) results in the formation of ADP (adenosine diphosphate), an inorganic phosphate, and the release of free energy.

Answer:

Question 1: a chemical that Closely mimics the structure of glucose but is not metabolized.
Question 2: NADH Dehydrogenase
Question 3: adenosine diphosphate, an inorganic phosphate, and free energy
