WebMar 25, 2024 · According to Nature, mitochondria produce ATP by passing a high-energy electron along an electron transport chain. The high amount of energy from this process pumps hydrogen out of the mitochondrial matrix. This creates a pressure gradient, which drives the hydrogen molecule back through the membrane. WebThe photons in light provide the energy that drives photosynthesis. This energy is used to incorporate carbon found in CO 2 from the atmosphere into organic molecules and, in particular, into simple sugars used by the plant. The chemical formula is the same for the two types of simple sugars produced by photosynthesis: glucose and fructose greenport ny tax assessor
