Multiple Choice QuestionsDuring which stage in the complete oxidation of glucose are the greatest number of ATP molecules formed from ADP?
Conversion of pyruvic acid to acetyl Co-A
Electron transport chain
Glycolysis
Krebs cycle
Chemiosmotic theory of ATP synthesis in the chloroplasts and mitochondria is based on
proton gradient
accumulation of K ions
accumulation of Na ions
membrane potential
Fat, prior to its oxidation associate with
cyclic AMP
Co- A
GMP
ATP
B.
Co- A
The respiratory decomposition of fatty acids is known as beta oxidation, which occurs in liver and adipose tissue. Activation of fatty acids takes place, then dehydrogenation of activated fatty acid takes place. It is followed by hydration. The -hydroxyl acyl derivative is converted to -keto derivative, which then reacts with Co-A. And it leads to oxidation.
The terminal electron acceptor during electron transport system is
oxygen
cyto a3
cyto c
plasto quinone
Assertion: Conversion of 1,3 biphosphoglycerate (BPGA) to 3-phospho-glyceric acid (PGA) is an energy yielding step.
Reason: This energy is trapped in the form of ATP
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.
Which enzyme helps in transfer of phosphate group from ATP to a carbohydrate
Phosphatase
ATPase
Phosphorylase
Catalase
Assertion: Glucose is the favoured respiratory substrate.
Reason: When glucose is used as respiratory substrate and is completely oxidized, the RQ is 1.
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
