c. a five-carbon sugar with two phosphates is required

d. sugars are made within the thylakoid spaces

multiple choice question someone help urgent!! ill upvote

Answer 1

Answer:- c) a five-carbon sugar with two phosphates is required

Photosynthesis takes place in two stages

1) light-dependent reactions

2)Calvin cycle (light-independent reactions).

The end product of calvin cycle(dark reaction) is synthesis of a six carbon sugar,which need input of carbon dioxide.To produce single molecule of six carbon sugar it joins six molecules of CO2 by six turns of the cycle.The first process is cooperation of CO2 with ribulose-1,5 bisphosphate which is a five carbon sugar with 2 phosphate group.The enzyme RUBISCO catalyzes carboxylation reaction.
