In the net formula of the CETCH (“ketch”) cycle, two moles of this molecule react in vitro to form a mole of gly·oxylate. This molecule is stored at extremely high concentrations inside Chlamydomonas (“kluh-MID-oh-moh-nuss”) pyrenoids and cyanobacterial microcompartments. (0[1])This molecule slowly (0[1])adds to the five-carbon acid RuBP and (0[1])splits it into (0[1])two molecules (0[1])of (20[1])3-phosphoglycerate. (20[6]0[1])This molecule (20[1])reacts with (0[1])PEP (“P-E-P”) to form oxalo·acetate (20[2])in mesophyll cells, then is (0[1])released from (*) C4 (10[1])acids inside bundle sheath cells. (10[2])In genus Crassulacea (10[1]0[1])(“crass-uh-LAY-shuh”), stomata uptake this molecule (10[1])at night (10[1])until enough ATP accumulates (0[1])to use it in the stroma during the (10[1])day. RuBisCo fixes this molecule in the Calvin (0[1])cycle. (0[1])For 10 points, chloroplasts consume water and what gas (10[3])to make sugars (10[1])during (10[1])photosynthesis? (10[5])■END■ (10[7]0[1])
