BIO 152 EXAM 3 WITH CORRECT
ANSWERS 2025
Aerobic vs. Anaerobic correct answers >> Aerobic - Complete
breakdown of glucose.
Anaerobic - Partial breakdown of glucose.
Aerobic - utilize carbs, fats, or proteins as fuel.
Anaerobic - only carbs as fuel.
Aerobic - Long-duration activity.
Anaerobic - Short-duration activity.
Aerobic - moderate intensity.
Anaerobic - Maximal work, high intensity.
Aerobic - Carbon dioxide and water are end products.
Anaerobic - Lactic acid is the by-product.
Aerobic - Uses oxygen in chemical breakdown.
Anaerobic - Doesn't need O2 in chemical breakdown.
cellular respiration correct answers >> CATABOLIC process
cellular energy is released for the cell to do work
,transfers electrons from molecules referred to as redox reactions
glycolysis correct answers >> first step in respiration in the
cytoplasm; anaerobic.
splits glucose in 2 ATP & 2 reduced NADH electrons.
phosphorylation correct answers >> addition of phosphate
group to organic (carbon based) molecule. addition of unstable
phosphate group increases overall energy state.
Oxidation vs. Reduction correct answers >> oxidation: lose
electrons
reduction: gain electrons
metabolic fuel correct answers >> carbs, lipids, proteins
produce ATP.
Use mostly LIPIDS for cellular respiration
lipids at rest, carbs at activity.
Catabolic vs. Anabolic correct answers >> Catabolic:
breakdown
Anabolic: builds/creates
metabolic water correct answers >> water produced during
cellular respiration
, cell metabolism correct answers >> collection of chemical
reactions in cell to maintain life.
(respiration is catabolic =ATP)
role of cell respiration in metabolism correct answers >>
multiple redox reactions produce efficient amounts of ATP.
2-3 ATP without, 32-36 ATP with
ATP cycle correct answers >> How a cell regenerates its ATP
supply. ADP forms when ATP loses a phosphate group, then ATP
forms as ADP gains a phosphate group.
how does the ATP cycle relate to cellular respiration/metabolism?
correct answers >>
two different ways to make ATP correct answers >>
substrate-level phosphorylation: high energy, needs enzyme to
transport through membranes
oxidative phosphorylation: low energy, free phosphate, only in
eukaryotes/bacteria
4 steps of cellular respiration correct answers >> 1.
Glycolysis
2. Pyruvate processing
3. Citric acid cycle
4. oxidative phosphorylation (electromechanical gradient)
