Biological oxidations are also called _______ reactions.
At the completion of the Krebs cycle, the carbons from glucose are in _____ (name the molecule)
Carbon dioxide (Co2)
At the completion of aerobic respiration, energy has been formed. The energy from the oxidation of glucose is stored in ____?
_______ involves an inhibitor that fills the active site of an enzyme and competes with the normal substrate for the active site.
For every NADH that is oxidized via the electron transport chain, _____ ATP are formed.
All of the following pairs are correctly matched EXCEPT
Oxidation; reaction where are gained.
Competitive inhibition of enzyme action evolves
competition with the substrate for binding at the active site.
During glycolysis, electrons from the oxidation of glucose are transferred to
Streptococcus ( In italics) bacteria lack an electron transport chain. How many molecules molecules of ATP can a Streptococcus (In italics) cell net from one molecule of glucose?
Unlike eukaryotes, in prokaryotes chemiosmosis
occurs at the plasma membrane and not the mitochondria.
The chemical reactions involved in synthesizing proteins and cell wall peptidoglycan are examples of _________ reactions.
For a cell wall, which of the following compounds has the greatest amount of energy per molecule?
Acetyl CoA pyruvate.
The complete oxidation of glucose typically involves which three stages?
Glycolysis, Krebs cycle, and the electron transport chain.
Which of the following mechanisms does not generate ATP using an electron transport train?
Which f the following are products of the light-dependent reactions, on which the light-dependent reactions are dependent
ATP and NADPH
Enzymes work most effectively at their optimal temperature and pH.
Feedback inhibition generally acts on the last enzyme in an anabolic pathway
Glycolysis produces ATP through substrate phosphorylation.
The synthesis of sugars by using carbon atoms from Co2 gas is called carbon fixation.
Lipids, proteins, and sugars all may serve as substrates of glycolysis.
