Which of the following phrases best describes the role of NADPH in photosynthesis?
It absorbs light energy. It allows protons across membranes.
It carries electrons from one stage of photosynthesis to the other.
It converts useless wavelengths of light into more useful ones for photosynthesis
. It prevents electron flow when no further energy is needed.
Answer : It carries electrons from one stage of photosynthesis to the other
Explanation: used in the light-independent reactions as a reducing agent in the Calvin cycle to reduce atmospheric carbon dioxide (CO2) producing monosaccharides for use by the plant for structure and energy.

Question 3 2 pts Which of the following describes which grow light would have been the best choice for the biosphere? The green light because it has a wavelength of 500-570 nm which is the wavelength that is best absorbed by chlorophyll. The blue light because it has a wavelength of approximately 450-500 nm which is the wavelength best absorbed by chlorophyll. The red light because it has a wavelength of 610-700 which is a unique wavelength for chlorophylla Any...

Respiration and the light reactions of photosynthesis have several features in common. Which of the following is NOT a common feature? O Both use an electron transport chain. Both couple the energy in Redox reactions to the translocation of protons across a lipid bilayer membrane. O Both have a primary function of reducing NAD+ to NADH Both can generate ATP by using the energy stored in a proton gradient to drive ATP synthase. Both require membranes for key reactions in...

ADP, Pi and NADP E. ATP and carbon dioxide QUESTION 2 Which of the following is a correct sequence of the cell cycle? QUESTION3 At various times, DNA was isolated from the nuclei of cells growing in cell culture. The measured DNA levels ranged from 3 to 6 picograms per nucleus. In which stage...

Lab 8 Spring 2020 The Light Reactions The light reactions begin with the photolysis of water. Photolysis refers to the process by which, in the Intact thylakoid membranes and light. water is split into oxygen protons and electrons. Therefore, was primary electron donor in photosynthesis. Conversion of water, a very stable molecule, to oxygen is er unfavorable and would not occur to any significant extent without input of light energy in photosystem e process by which,...

D Question 19 2 pts Which of the following statements best describes the primary role played by oxygen in cellular respiration? It yields energy in the form of ATP as it is passed down the electron transport chain. It serves as an acceptor for carbon, forming CO2 in the citric acid cycle. It oxidizes glucose to form two molecules of pyruvate. It serves as the final acceptor for electrons from the electron transport chain. Question 20 2 pts Which of...
6. Which best describes how a p-n junction operates as a solar cell? a. Incoming photons heat up the semiconductor, thus promoting electrons into the conduction band, leaving behind a hole in the valence band. The junction E-field pushes the electron and hole in opposite directions causing a current to flow. b. Incoming photons are absorbed by an electron near the junction, promoting it from the valence band to the conduction band and leaving behind a hole in the valence...
