Answer:
ATP and NADPH
Explanation:
The second stage of the Calvin cycle is the reduction in which 3-Phosphoglycerate is reduced into Glyceraldehyde 3-phosphate by a series of reactions. These reactions consume ATP as an energy source and NADPH as an electron donor. ATP and NADPH for produced during the light-dependent phase of photosynthesis. Transfer of electron through ETC generates proton concentration gradient across the thylakoid membrane which in turn drives ATP synthesis. Electrons released from water splitting finally reach NADP reductase enzyme that reduces NADH into NADPH.
b) some bacteria reduce nitrate ion
Hi there! The level of carbon dioxide affects the global temperature, because it causes heat to be trapped into the atmosphere and heat the Earth up. CO2 (formula for carbon dioxide) is a naturally made gas formed by breathing, but lots of it is bad for the planet. Human activities like driving cars and running factories add much more toxic gasses into the environment. Global warming is the cause of melting ice caps, which leads to rising sea levels, and is also the cause of some plant and animal species dying out.
