Question

2) True or False? Enzymatic reactions required for the Calvin cycle take place in the stroma

3) True or False? G- proteins become activated when a kinase phosphorylates the GDP bound to inactive G-proteins

4) True or False? Growth factors can initiate entry into s phase during the G1 checkpoint by indirectly causing the phosphorylation of Rb, releasing F2F

5) True or False? cyclic electron flow is used only when plants are at risk of becoming dehydrated.

6) True or False? O2 gas is an oxidized product of the photosynthetic reaction.

Answer 1

2) ANSWER : TRUE

EXPLANATION : Photosynthesis takes place in chloroplast , calvin cycle take place in the stroma. The light energy from the sun is absorbed and converted into chemical energy and stored in the molecules of NADPH and ATP

3)ANSWER :  TRUE

EXPLANATION : The in activation of the G protein occurs when G-alpha bounds to GDP to form an inactivated G protein that can be associated with the receptor

4)ANSWER : FALSE

EXPLANATION : The regulation of RB phosphorylation , which controls the functions of E2F factors

5) ANSWER : TRUE

EXPLANATION : Cyclic electron flow plays the major role to have photo protection in the green plants, This technique is used to protect the rare species.

6) ANSWER : TRUE

EXPLANATION : During photo synthesis reaction loss of electron takes place in the water molecules and O2 becomes oxidized product
