Question

Which of the following events accompanies absorption of energy by chlorophyll molecules of the reaction-center complex? A) An electron is excited. B) A molecule of water is split. C) NAD+ is reduced to NADH. D) ATP is synthesized from the energy absorbed. 6) What are the products of linear electron flow during the light reactions of photosynthesis? A) ATP and P700 B) ATP and NADPH C) heat and fluorescence D) ADP and NADP+

Answer 1

A) an electronic is excited

Step-by-step explanation:

An electronic is the correct answer

Answer 2

B

Step-by-step explanation:

The energy harnessed from the sun is used to split a water molecule into 2H+ and O-. In this process, called photolysis, high energy electrons are released and are used to replaced the electrons that have moved from the reaction center of photosystems to be passed down the photosystem protein chain. As the electron from the reaction center passes down this protein chain, their energy is harnessed to pumps H+ ions from the stroma into the lamellae. This proton motive force will then be used to create ATPs by ATP synthase.
