Question
What is the electron carrier in photosynthesis?
Solution
The electron carrier in photosynthesis is a molecule called NADP+ (Nicotinamide adenine dinucleotide phosphate). Here's a step-by-step explanation:
-
Photosynthesis begins with the absorption of light by pigments in the chloroplasts of plant cells. The most important of these pigments is chlorophyll-a.
-
The energy from this light excites electrons in the chlorophyll-a, causing them to reach a higher energy state.
-
These high-energy electrons need to be transferred to another molecule to be used in the creation of glucose, the end product of photosynthesis.
-
This is where NADP+ comes in. It accepts these high-energy electrons, along with a hydrogen ion (H+), to become NADPH.
-
NADPH then carries these high-energy electrons to the next stage of photosynthesis, the Calvin cycle. Here, they are used to convert carbon dioxide (CO2) into glucose.
So, in summary, the electron carrier in photosynthesis is NADP+.
