Potassium ions are pumped into the cell, against their concentration gradient. An electrochemical gradient is formed. All of the above statements are true. Electron transport and chemiosmosis e. More than one pathway shown above.
Anaerobic respiration takes place in a. the chloroplast.
The enzyme triose phosphate dehydrogenase carries out two reactions. The second reaction is the transfer of free phosphate to glyceraldehyde phosphate, forming 1, 3-bis phosphoglycerate. Pyruvate is also formed in this step. Pyruvate enters the mitochondrion. Pyruvate immediately enters the Krebs cycle.
