If a plant fails to get water for almost 2 weeks, what will happen during photosynthesis, and what will happen to the plant? How do keystone species contribute to the trophic structure of an ecosystem? Explain how the inhibitions of reactions by molecules ATP, ADP, and citrate affect...
Describe the process of photosynthesis, including the structure and function of photosystem 1, photosystem 2, cyclic electron transport, ATP synthesis and the Calvin Cycle. How are ATP, ADP, NADP+, and NADPH cycled in photosynthesis? Which sequence accurately reflects th...
During oxygenic photosynthesis, light energy transfers electrons from water (H2O) taken up by plant roots to CO2 to producecarbohydrates. In this transfer, the CO2 is "reduced," or receives electrons, and the water is "oxidized," or loses electrons. Oxygen is produced along with carbohydrates. ...
Adenosine triphosphate, or ATP, is another molecule produced when light energy is converted to chemical energy via the electron transport chain. Like NADPH, it also provides energy thatchloroplastsuse to make sugar from carbon dioxide. ATP forms when a phosphate group is added to ADP, adenosine d...
2 H2O + 2 NADP++ 3 ADP + 3 Pi+ light → 2 NADPH + 2 H++ 3 ATP + O2 In the dark stage, ATP and NADPH ultimately reduce carbon dioxide and other molecules. Carbon dioxide from the air is "fixed" into a biologically usable form, glucose. In plants, algae, and cyanobacteria, the...
The hydrogen converts to NADPH which is then used in the light-independent reactions. Oxygen diffuses out of the plant as a waste product of photosynthesis and ATP is synthesised from ADP and inorganic phosphate. This all happens in the grana of chloroplasts. ...
In photosynthesis H+ ions are vital in the production of the energy source that is ATP, which is used in several metabolic processes, such as respiration. The photolysis of water produces H+ ions, electrons and O2. The excited electrons lose energy as they move along the electron transport ...
What is plant stroma? Stroma, in botany, refersto the colorless fluid surrounding the grana within the chloroplast. Within the stroma are grana (stacks of thylakoid), and the sub-organelles or daughter cells, where photosynthesis is commenced before the chemical changes are completed in the stroma...
Which of the following processes is exergonic? A) The synthesis of glucose from carbon dioxide and water. B) Photosynthesis. C) The breakdown of glucose. D) ADP + Pi to ATP. E) Answers B and D are both correct. How does ATP contribute to metabolic reactions? A. Hydrolysis of ATP pro...
On the other hand, ATP Synthase is a specific enzyme complex found in the mitochondria of eukaryotic cells and in the thylakoid membrane of chloroplasts in plants. It plays a pivotal role in cellular respiration and photosynthesis by synthesizing ATP from ADP and inorganic phosphate. This process ...
