Denaturation occurs when…
temperature of pH are outside of an enzymes optimal range altering its shape and stopping it from functioning correctly
Ribozymes are…
RNA molecules with catalytic activities that form part of a ribosome
Respiration is…
an efficient type of energy production method involving organic molecule oxidation
Aerobic respiration is…
a type of respiration that uses oxygen as the terminal electron acceptor
Anaerobic respiration is…
a type of respiration that uses alternatives to oxygen as terminal electron acceptors
Fermentation is…
an inefficient energy production method involving only substrate-level phosphorylation
Substrate-level phosphorylation is…
the enzymatic transfer of a phosphate group from high-energy substrate to ADP, forming ATP
Stage 1 of aerobic respiration:
Macromolecules are broken into monomers
Stage 2 of aerobic respiration:
Glucose undergoes glycolysis
Glycolysis is an…
anaerobic proccess
Glycolysis converts six-carbon glucose into…
two three-carbon pyruvate molecules
Glycolysis produces…
ATP and NADH
Three carbon pyruvate converts to…
two-carbon Acetyl-CoA which yeilds NADH
Glycolysis occurs in the…
cytoplasmic matrix
Stage 3 of aerobic respiration:
Acetyl-CoA is oxidized by the tricarboxylic acid (Krebs) cycle, producing small amounts of ATP and large amounts of NADH and FADH2
The Krebs Cycle is an…
amphibolic pathway
The net products of glycolysis are…
two molecules each of ATP, NADH, and pyruvate
During the linking step between glycolysis and the Krebs cycle…
pyruvate converts to two-carbon Acetyl-CoA, yeilding NADH and releasing CO2
The step linking glycolysis and the Krebs cycle occurs in the…
cytosol
For each acetyl-CoA entering the citric acid cycle there are…
Three NADH, one FADH2, one ATP, and two CO2`
