User: What is required for both the light-dependent and light-independent reactions to proceed? Practice: Photosynthesis. 60 seconds . Q. energy CO2 water ATP and NADPH Weegy: ATP is required for both light-dependent and light-independent reactions. Photosynthesis is a photo-chemical reaction involving 2 main steps, i.e. Which chemical is an electron carrier molecule? products of one set of reactions becomes a reactant, appears green because it reflects green light, such as carotenoids( help absorb the wavelength of light), converting light energy to chemical energy, a cluster of pigments; chlorophylls and carotenoids ( PS2 and PS1), energy is absorbed by pigments and gets passed around the pigment molecules until it reaches chlorophyll a, shines = electrons in chlorophyll(PS2) go into higher energy level, a reduction reaction then occurs => the electron is accepted by a primary electron acceptor, electron passed down electron transport chain, meanwhile PS1 has shining on it => electrons get excited and go to primary electron acceptor which goes down electron transport chain, at end of electron transport chain electron combines with NADP+ and a H+ to make NADPH, accumulate within thylakoid= creates concentration gradient. Chloroplasts contain saclike photosynthetic membranes called? This is the currently selected item. answer choices . Light independent reactions depend on light dependent reaction for supply of APT, NADPH. What are the two stages of photosynthesis? The elemental oxygen in water molecule combines with another oxygen from another water molecule to form oxygen molecule. SURVEY . ADP. answer choices . H 2 O. carbon dioxide. The overall function of light-dependent reactions is to convert solar energy into chemical energy in the form of NADPH and ATP. SURVEY . In light reations, ATPs, NADPHs and oxygen … During the light-independent reactions, ATP and NADPH (from light dependent reaction) and 3 molecules of CO2 are used to create glucose. G3P. 5 C NADPH is made during the light reactions and passed to the Calvin cycle. answer choices . Sort by: Top Voted. ATP. An electrochemical gradient is a gradient of electrochemical potential, usually for an ion that can move across a membrane.The gradient consists of two parts, the chemical gradient, or difference in solute concentration across a membrane, and the electrical gradient, or difference in charge across a membrane.
