Pregunta 5
Pregunta
Which of the following statement about alcohol / lactic acid fermentation is incorrect?
Respuesta
-
Oxygen is not the terminal electron acceptor.
-
NAD+ produced during fermentation can be reused during glycolysis to generate ATP.
-
Oxygen is the terminal electron acceptor.
-
Processes require another electron acceptor to replace oxygen.
-
Fermentation allow the cell to oxidize NADH back to NAD+ in the absence of oxygen.
Pregunta 6
Pregunta
Which of the following statements about ATP is correct?
Respuesta
-
The key to how ATP stores energy is in the diphosphate.
-
The phosphate groups are highly positively charged, therefore they repel each other.
-
The bonds between the phosphate groups are stable, having a positive ΔG
-
The bonds between the phosphate groups are easily broken by a condensation relation
-
None of the above
Pregunta 7
Pregunta
The oxidative phosphorylation involves:
Respuesta
-
the flow of protons across the inner mitochondrial membrane down their concentration gradient.
-
the flow of electrons through a large enzyme called ATP synthase.
-
the flow of electrons through the electron transport chain proteins located in the outer mitochondrial membrane.
-
the flow of protons across the outer mitochondrial membrane down their concentration gradient.
-
generating potential energy in the form of a pH gradient between the mitochondrial matrix and the cell cytoplasm.
Pregunta 8
Pregunta
How is ATP produced by glycolysis?
Respuesta
-
Through the priming reactions
-
Through the production of glyceraldehyde-3-phosphate
-
By substrate-level phosphorylation
-
As a result of the reduction of NAD+ to NADH
-
By oxidative phosphorylation
Pregunta 9
Pregunta
Which of the following is a correct definition of catabolism?
Respuesta

set of chemical reactions that occur in living organisms in order to maintain life
-
set of metabolic pathways which breakdown molecules into smaller units and release energy
-
set of metabolic pathways that construct molecules from smaller units
-
process by which the body breeaks down food so it can be absorbed by the blood stream
