PHOTOSYNTHESIS

LIGHT DEPENDENT REACTIONS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
It is important to create a concentration of H+ in the thylakoid space so that the H+ can diffuse through ____ to create ____
A
ATP synthase, ATP
B
NADH, NADPH
C
proton pump, protons
Explanation: 

Detailed explanation-1: -The hydrogen ions are allowed to pass through the thylakoid membrane through an embedded protein complex called ATP synthase. This same protein generated ATP from ADP in the mitochondrion.

Detailed explanation-2: -This gradient is used to power oxidative phosphorylation by ATP synthase to create ATP.

Detailed explanation-3: -A large number of H+ ions accumulate in the thylakoid space as a result of photolysis and electron transport. This creates a concentration gradient across the thylakoid membrane. – The thylakoid space has more Hydrogen than the stroma.

Detailed explanation-4: -In Summary: The Light-Dependent Reactions of Photosynthesis Energy travels through the electron transport chain, which pumps hydrogen ions into the thylakoid space.
