Document Summary
1. 3 cells require energy: the reason that we consume food, is to provide fuel to our body to synthesize energy in the form of. Atp: our cells need energy for many things, including housekeeping activities such as: Dna replication, cell division, protein synthesis, maintaining an osmotic gradient of sodium and potassium ions all of these processes require energy. 1. 4 nutrient breakdown generates energy macronutrients that provide fuel to the cells recall that there are three for energy production: carbohydrates, lipids. Carbs: glucose is broken down to and proteins. pyruvate through glycolysis, To acetylcoa via the pyruvate dehydrogenase reaction, then to carbon dioxide through the citric acid cycle. Fadh2, that are generated from these processes are then converted to atp through the electron transport chain and oxidative phosphorylation. Lipids: fats are broken down from triacylglycerols to free glycerol and fatty acids.
