Answer:
B) Conversion of 3PG to G3P
Explanation:
Conversion of 3PG (3 phosphoglycerate) or 3 phosphoglyceric acid is a reduction reaction step of the Calvin cycle, it does not take place during light reaction of the photosynthesis. The 3PG is converted into molecules of glyceraldehyde-3-phosphate (G3P) using ATP and NADPH. Generation of NADPH from NADP+, Photolysis or splitting of splitting of water that releases an electron and synthesis of ATP from ADP + Pi occurs during light reactions.
Unlike arteries, veins contain valves that ensure blood flows in only one direction. (Arteries don't require valves because pressure from the heart is so strong that blood is only able to flow in one direction.) Valves also help blood travel back to the heart against the force of gravity.

Things that get left behind from a long term member
Oxygen molecules are too small and glucose molecules are quite large than oxygen. So they can't passively disuse inside a cell.
Option C
<h3><u>Explanation:</u></h3>
Glucose molecules are large molecules with a molecular formula of C₆H₁₂O₆ These molecules need special protein channels or transporters called Glucose Transporters or GLUT to make them way through the cell membranes. While smaller molecules like oxygen, carbon dioxide, smaller polar molecules like <em>water</em> or even fat soluble molecules like chloroform and benzene do pass through the membranes easily by means of passive diffusion.
The oxygen molecules are needed inside a human cell for aerobic respiration and glucose molecules are needed because of a respiratory substrate. So Glucose needs receptors and transporters to pass through the membranes.
