Answer:
A
Explanation:
The light energy from sunlight in photosynthesis is used to split the water molecule into H+ and O2-. The H+ is then used to reduce NADP+ to NADPH. Through photophosphorylation, the energy from the sun is also used to make ATP from ADP. As the electrons are passed from one protein to the other in the chain, the energy released is what is used to create ATP.
Oxygen is evolved out as a byproduct
NADP+ + 2e- + 2H+ --> NADPH + H+
Answer:
I believe it is A, it is a crucial part of the process
Answer:
Due to less steps and requires less energy.
Explanation:
The bacterial cell is able to use glucose first as an energy source then switch to lactose because glucose requires less steps and less amount of energy for the break down as compared to lactose. If lactose is the only sugar available to the bacterial cells, then bacterial cells will use it as energy source for the production of energy. In order to use lactose, the bacteria must express the lac operon genes, which encode the main enzymes for lactose uptake and metabolism.
