Question

Trace the flow of carbon from the atmosphere to glyceraldehyde-3-phosphate within a CAM plant. Drag the terms on the left to the appropriate blanks on the right to complete the sentences. Terms can be used once, more than once, or not at all.

CO2 (in cytosol)
a. stomata
b. Calvin cycle
c. malate (in vacuole)
d. oxaloacetate (in cytosol)
e. bicarbonate
f. malate (in cytosol)
g. mesophyll cell
h. glyceraldehyde-3-phosphate

Answer 1

Step-by-step explanation

mesophyll cell----- calvin cycle

Calvin cycle-----glyceraldehyde-3-phosphate

Cam plants mean crassulacean metabolic pathway.

This plant undergoes photosynthesis by seperation in time in other to reduce photorespiration.

Cam plants opens their stomata at nights, absorb Carbondioxide and store as oxaloacetate with the help of phosphoenol pyruvate carboxylase an enzyme that helps ferry co2 into the cell, oxaloacetate is then converted into malate and other organic acid and then stored in the vacoule. In the day the stomata closes and the stored malate is released from vacoule are broken down into pyruvate and CO2 in the mesophyll cell. The CO2 is then used in the calvin cycle to produce the G3P while pyruvate goes back to the cycle.
