Who has proved that oxygen evolved in photosynthesis comes from water?
Cornelius van Niel
Which light range is most effective in photosynthesis?
The best wavelengths of visible light for photosynthesis fall within the blue range (425–450 nm) and red range (600–700 nm). Therefore, the best light sources for photosynthesis should ideally emit light in the blue and red ranges.
What is the role of NADP plus in photosynthesis?
NADP+ functions as a carrier to transfer high energy electrons from chlorophyll to other molecules.
What is needed for light-dependent reactions?
The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH. In plants, the light reactions take place in the thylakoid membranes of organelles called chloroplasts.
Which enzyme is important in photosynthesis and what is its function?
Carbonic anhydrase, an enzyme which catalyzes the reversible hydration of CO2, is a major protein component of most photosynthetic microorganisms and higher plant tissues.
Is used ATP discarded by the cell?
ATP provides energy for the mechanical functions of cells. Used ATP is discarded by the cell as waste.
Which enzyme is responsible for the splitting of ATP?
The last step in glycolysis is catalyzed by the enzyme pyruvate kinase (the enzyme in this case is named for the reverse reaction of pyruvate’s conversion into PEP) and results in the production of a second ATP molecule by substrate-level phosphorylation and the compound pyruvic acid (or its salt form, pyruvate).
Does ATP contain less stored energy than ADP?
Thus, ATP is the higher energy form (the recharged battery) while ADP is the lower energy form (the used battery). When the terminal (third) phosphate is cut loose, ATP becomes ADP (Adenosine diphosphate; di= two), and the stored energy is released for some biological process to utilize.
Does ATP contain 5 phosphate groups?
Adenosine-5′-triphosphate (ATP) is comprised of an adenine ring, a ribose sugar, and three phosphate groups.
