The answer is B. This the systolic pressure of a giraffe in comparison
to that of a human that is 100 mm Hg. This
high blood pressure ensures that the giraffe maintains 100 mmHg in the brain.
Since a high BP impairs gas exchange and increases transpulmonary filtration,
the pulmonary circulation must be separated. Therefore, in the giraffe, there
is a relatively great difference between the right ventricular and left ventricular
maximal rates of pressure ascent, the left ventricular rate of ascent being 5
times that calculated for the right ventricle.
Answer:
A. The synthesis of triose phosphates from 3-phosphoglycerate
Explanation:
ATP and NADPH are produced during light-dependent reactions of photosynthesis in chloroplasts. These molecules serve as an energy source and reducing power respectively during the Calvin cycle. Calvin cycle includes fixation of carbon into 3-PGA followed by reduction of 3-PGA into glyceraldehyde 3-phosphate (a triose phosphate).
The reduction step also uses NADPH as an electron donor. Two molecules of glyceraldehyde 3-phosphate make one molecule of glucose. A reduced ATP production during light-dependent reactions in chloroplast would not allow the reduction of 3-PGA into glyceraldehyde 3-phosphate. Without the formation of triose phosphate, glucose synthesis will also reduce.
