Multiple Choice: Metabolic Processes

Question 1

What happens to NAD+

Answer 1

Reduction: NAD+ gains electrons from a hydride to form NADH
Oxidation: NADH loses its hydride electron to become NAD+

Question 2

Products of light dependant reactions in photosynthesis

Answer 2

water molecules are split as light energy is absorbed and transformed into chemical energy in ATP and NADPH

Question 3

The generation of concentration gradients in the mitochondria

Answer 3

An H+ gradient (proton)
Conplexes of the electron transport chain undergo redox reactions that, in turn, generate energy to pass up its gradients

Question 4

Fermentation in respiration

Answer 4

a process that uses an organic compound as the final oxidizing agent to produce energy

Question 5

Assembly’s of sugars during photosynthesis

Answer 5

1. light-dependant reaction’s that produces ATP & NADPH
2. Calvin cycle which converts ATP, NADPH & CO2 to glucose and makes ADP + Pi & NADP+ to be used for light dependant reactions
