Which of the following statements regarding photosynthesis are true and which are false? T = true and F = false. A) resonance energy transfer does not include the transfer of an electron B) the P680 reaction center in photosystem II can extract electrons from water because the redox potential of "activated" P680 has a redox potential more positive than that of water. C) two photons must be captured to move an electron from water to NADP+ during oxygenic photosynthesis D)...

Diagram the major steps for the light reactions of photosynthesis, showing the path of electrons. Show PS I and PS II in the correct order. Always show electron donors and electron acceptors. The diagram should somehow show net reduction potentials (delta epsilon), indicating when they are positive or negative. In the diagrams of the mitochondrial ETC and the light reactions of photosynthesis, show the ultimate donor of electrons and the ultimate acceptor of electrons.

Kermit the frog is green because: Select one: he absorbs all wavelengths of light he reflects short wavelengths of visible light he absorbs mid wavelengths of visible light he reflects long wavelengths of visible light he reflects mid wavelengths of visible light 2. In photosynthesis chemiosmosis occurs due to: Select one: H+ flowing down a concentration gradient, resulting in NADPH production P680+ being reduced to P680 H+ flowing down a concentration gradient, resulting in ATP production electrons flowing down...

1a. Choose the false statement: Group of answer choices According to their absorption spectra, chlorophylls a and b are not able to absorb those wavelengths of light that coincide with green light. The role of water in photosynthesis is to provide a source of electrons to replace those ejected from reaction center chlorophyll a when it is activated by light energy. When the light reactions are completed (at the end of the Z-scheme), all the electrons excited by the sun...

I have provided the information for the lab below. I want to see the chemical reactions that take place during each step of the experiment. So in the procedures when a chemical was added i would like to see what the products and byproducts that were formed. I also want to see one over all reaction for this experiment to just get an overview of what exactly is happening during the experiment. Thank you:) Part B: Synthesis of [Co(NH3)5Cl]Cl2 Objective:...

1 In the absence of oxygen, cells consume glucose at a high, steady rate. When oxygen is added, glucose consumption drops precipitously and is then maintained at the lower rate. Why is glucose consumed at a high rate in the absence of oxygen and at a low rate in its presence? 2 In the following diagram showing the distribution of thermal energy in a population of substrate molecules, the energy thresholds indicated by numbers represent ... Energy per molecule Number...
