AP Biology Semester 1 review 2024/25; Questions &
Answers Latest Update 100% Solved
Glycolysis Correct answer-reactions, carried out in the cytoplasm, that break down
glucose into two molecules of pyruvate (3 carbon molecule), producing two ATP molecules
Activation Energy Correct answer-The energy needed to start a chemical reaction
Calvin Cycle Correct answer-Synthesizes sugar from the energy captured in ATP and
NADPH in the light reactions -associated with the stroma
Active Site Correct answer-The region of an enzyme molecule that binds substrates and
performs the catalytic function of the enzyme.
Aerobic Respiration Correct answer-oxygen-requiring reactions, occurring in
mitochondria
Adenosine Diphosphate (ADP) Correct answer-A molecule composed of the sugar ribose,
the base adenine, and two phosphate groups
Matrix Correct answer-the fluid contained within the inner membrane of the
mitochondrion
Krebs Cycle (citric acid cycle) Correct answer-cycle series of reactions in which pyruvate
molecules produced are broken down to CO2, forming ATP and NADH

Answers Latest Update 100% Solved
Light Reactions Correct answer-Chlorophyll and other molecules capture sunlight energy
and convert it to chemical energy stored in ATP and NADPH-associated with the thylakoid
Adenosine Triphosphate (ATP) Correct answer-A molecule composed of the sugar ribose,
the base adenine, and three phosphate groups.
Noncompetitive Inhibition Correct answer-
Lactic acid fermentation Correct answer-A series of anaerobic chemical reactions using
pyruvic acid that follows glycolysis and regenerates the NAD+ needed for glycolysis to occur.
Produces Lactic Acid, occurs in bacteria and human muscle cells experiencing oxygen debt.
Alcoholic fermentation Correct answer-A series of anaerobic chemical reactions using
pyruvic acid. Follows glycolysis and regenerates the NAD+ needed for glycolysis to occur.
Produces alcohol and CO2 as byproducts, used by yeast cells in anaerobic conditions.
Competitive Inhibition Correct answer-The process by which two ore more molecules
that are somewhat similar in structure compete for the active site of an enzyme.
Stoma (stomata) Correct answer-Pores in the epidermis-mouths of the plant-open and
close to exchange CO2, O2, and H2O vapor

Answers Latest Update 100% Solved
Endergonic Correct answer-Pertaining to a chemical reaction that requires an input of
energy.
Stroma Correct answer-Fluid enclosed in the chloroplasts
Enzyme Correct answer-A protein catalyst that speeds up the rate of specific biological
reactions.
Thylakoid Correct answer-Inner most membrane of chloroplast arranged into disk shaped
stacks.
Exergonic Correct answer-Pertaining to a chemical reaction that liberates energy (either
as heat or in the form of increased entropy); a "downhill" reaction.
Metabolism Correct answer-The sum of all chemical reactions that occur within a single
cell or within all cells of a multicellular organism.
Cell size is limited by Correct answer-surface to volume ratios
water potential gradient Correct answer-The maximum value is 0. More solute= lower
water potential (becomes a negative value)
