BIL 150 Bioenergetics (Mallery) WITH COMPLETE
SOLUTIONS
Metabolism correct answers catalytic reaction (run by enzymes) in cells
Anabolic pathways correct answers Takes small inorganic molecules and builds larger ones
Biosynthesis symbolized via photosynthesis—synthesis of ATP and NADPH and reduction
(add electrons) of CO2 to CH2O
Catabolic pathways correct answers Breaking down—chemical oxidation of food via cell
respiration
Digestion of polymers (carbs to glucose) via hydrolysis reaction
> Glycolysis
> KREBS cycle
> Electron Transfer
> ATP Synthase
Energy correct answers The capacity to do work
Work correct answers A measurement of change in a system over time
Kinetic energy correct answers Energy of motion
Potential energy correct answers Stored energy (capacity to do work eventually)
Heat correct answers Energy associated with movement of molecules in a body of matter;
most random form of energy (wasted)
First law of thermodynamics correct answers Energy can be transferred and transformed, but
it cannot be created or destroyed.
Second law of thermodynamics correct answers Every energy transfer or transformation
increases the entropy of the universe.
Entropy correct answers A measure of disorder in a system
How cells make ATP correct answers 1. substrate level phosphorylation
2. oxidative phosphorylation
3. photophosphorylation
substrate-level phosphorylation correct answers Where a substrate (with high-energy
phosphorylate intermediate on it) molecule donates its P to ADP, making ATP
The enzyme-catalyzed formation of ATP by direct transfer of a phosphate group to ADP
from an intermediate substrate in catabolism.
