#1: What happens to the heat generated when a cell does work (chemical, transport, or mechanical)?
It is lost to the environment
2) Which of the following occurs in glycolysis?
Glucose is converted to pyruvate
#3: Spontaneous chemical reactions have a [positive/negative] free energy. Enzymes increase the [rate/direction] of reactions by [increasing/decreasing] the energy of activation but [do/do not] change the ΔG of the reaction.
negative, rate, decreasing, do not,
#4: TRUE or FALSE: A cell at equilibrium is a dead cell.
True
#5: The ΔG of an enzyme catalyzed reaction was measured in lab and was -20 kcal/mol. If you repeat the experiment with twice the amount of enzyme, what will the ΔG of the new reaction be?
-20 kcal/mol
#6: Molecule D inhibits its own synthesis via a negative feedback pathway; which part of the pathway is it MOST LIKELY to interact with?
Enzyme 1
#7: Chemical reactions that build large molecules from smaller molecules are------- reactions; an example of this type of reaction in a metabolic pathway is-------.
Anabolic / photosynthesis
#9: TRUE vs FALSE: Fermentation is an anabolic and anaerobic process that does not need ATP
False
#10: TRUE vs FALSE: Molecule Y is an allosteric regulator of an enzyme, which means it binds to the active site of the molecule and prevents the enzyme’s ligand from binding, thereby inhibiting the enzyme’s activity.
False
#11: ATP is formed by chemiosmosis during which two processes?
Oxidative Phosphorylation and the Light Reactions
#13: Fermentation is important in organisms because it
Regenerates NAD+
#14: In the Krebs Cycle, which occurs in the _____________________, the rest of the carbon from glucose is converted to ____________, and more _______ , which is made by __________________.
mitochondrial matrix, CO2, ATP, substrate level phosphorylation
