Answer:
The correct answer is E the light reaction provide ATP and NADPH to the calvin cycle,and the cycle returns ADP,pi and NADP+ to the light reactions.
Explanation:
The light reaction of photosynthesis occur in the .During light reaction ATP is produced by cyclic photo phosphorylation and NADPH is generated by the reduction of NADP+ during Z scheme.
The ATP and reducing equivalent NADPH that is generated during light reaction is being utilized in the dark reaction.
During dark reaction both utilized ATP and NADPH are converted to ADP,pi and NADP+.These products are used during light reaction.
NADP+ is generated by the oxidation of NADPH and ADP and pi are produced by the hydrolysis of ATP.

There are choices for this question namely:
Carvedilol
Betaxolol
Acebutolol
Propranolol
Metoprolol
The correct answers are "betaxolol", "acebutolol",and "metoprolol". These drugs are from the class called beta blockers as they inhibition the action of beta receptors in the heart leading to a decrease in heart rate and blood pressure. There are also beta receptors in the bronchial tree, an inhibition of which will lead to bronchoconstriction.
Betaxolol, acebutolol, and metoprolol are cardioselective beta blockers and only blocks the beta receptors located in the heart. Carvedilol and propranolol are non-selective beta blockers that can cause bronchoconstriction which is contraindicated in patients with asthma.
