From which component of the light-dependent reactions does NADPH form most directly?

a. photosystem II

b. photosystem I

c. cytochrome complex

d. ATP synthase

Short Answer

Expert verified

From photosystem I component of the light-dependent reactions does NADPH form most directly. Option (b) is the correct answer.

Step by step solution

01

Introduction

Light-dependent reactions are also those who take place in the context of sight (photons).

When responsive proteins are aroused by daylight or any sky light, the reacts. Molecules have an important role as in event. They translate solar into electric charge and retain this one in glucose and chemical energy.

02

 Incorrect option (a), (c) and (d) 

Resulting from the rapid with marked the emergence in photosystem II. The antenna pigment's compound collects photons of light in the reaction Centre of photosystem II (PSII). The photosynthesis substance's electron is generated, thus launches the electron transfer cycle. Such electrons are then taken by photosystem I (PSI), ending in NADPH creation (reduced nicotinamide adenine dinucleotide phosphate).

The hemoglobin compound permits materials to pass the thylakoid membrane and it does not actually generate NADPH.

ATP synthase is just an enzymes that tends to make ATP, but that it can't seem to make NADPH itself.

03

 Correct option (b) 

Whenever a energy from PSII contacts PSI and is ignited with another photon, NADP (oxidized adenosine diphosphate phosphate) be reducing to NADPH. PSI has to be the most conventional way of NADPH.
