During photosynthesis, light energy is used by photosystems I and II to establish electron flow, which ultimately results in the production of ATP and NADPH. Two modes of electron flow exist, a linear electron flow and a cyclic electron flow (CEF). The latter pathway generates more ATP, but...
and ATP and NADPH are required. Therefore, photorespiration appears to be a very wasteful process in which net CO2fixation is reduced and energy is also used up in the process. Any factor that reduces the availability of CO2or increases the availability of O2to rubisco will increase the levels...
(decreased amount of chlorophyll and antenna protein, alteration in photosystem I and photosystem II components), enhancement of energy transfer (ferredoxin, H+ translocating NADPH-NAD+ to NADH-NADP+ transhydrogenase, and components of the oxidative phosphorylation pathway), and increased protein ...
The overall function of light-dependent reactions is to convert solar energy into chemical energy in the form of NADPH and ATP. This chemical energy supports the light-independent reactions and fuels the assembly of sugar molecules. The light-dependent reactions are depicted in Figure 13. Protein ...
What is the purpose of NADH? Why do humans need NADPH? The energy in glucose cannot be released by what system in photosynthesis What role does glucose play in cellular respiration? Why should plants require both chloroplasts and mitochondria? Can they live without either one?
Plants perform cellular respiration to produce: a. ATP. b. NADPH. c. Sugar. d. Oxygen. In which organelle does photosynthesis take place? Chemiosmosis of H^+ ions accumulate: a. inside the chloroplast. b. near the outer membrane. c. in the stroma. d...
Plants rely on solar energy to synthesize ATP and NADPH for photosynthetic carbon fixation and all cellular need. Mitochondrial respiration is essential in plants, but this may be due to heterotrophic bottlenecks during plant development or because it is also necessary in photosynthetically active cells...
center (RC) pigment, exciting an electron. This high-energy electron is lost from the RC pigment and passed through an electron transport system (ETS), ultimately producing NADH or NADPH and ATP. A reduced molecule (H2A) donates an electron, replacing electrons to the electron-deficient RC ...
only NADPH can be formed - not ATP. d. it occurs only in green plant TRUE or FALSE: A. In the dark, plants carry out both photosynthesis and respiration B. In the light, plants carry out both photosynthesis and respiration C. Animals are capable of respiration but not pho...
a. Carbon is reduced and NADH is oxidized. b. Carbon is oxidized and NADP^+ is reduced. c. Carbon is oxidized and NADPH is reduced. d. Water is reduced and oxygen is oxidized. e. Carbon is reduced and In photosynthesis, wh...
