What is the energy source used for aerobic cellular respiration?

Glucose is the ultimate energy source for aerobic cellular respiration, though this compound is broken down into pyruvate during glycolysis, a starting pathway common to aerobic cellular respiratio... Read More »

Which part of cellular respiration uses the most energy?

Through cellular respiration, eukaryotic cells derive about 40 molecules of ATP energy from each molecule of glucose. However, cells must invest energy to start this process. In the step that uses ... Read More »

What is the activation energy in cellular respiration?

Cell respiration is the way that cells use the energy from food to release energy. The process takes place in organelles called mitochondria, using proteins called enzymes. Enzymes speed up the rat... Read More »

How Is Oxygen Important to the Release of Energy in Cellular Respiration?

Aerobic cellular respiration is the process by which cells use oxygen to help them convert glucose into energy. This type of respiration occurs in three steps: glycosis; the Krebs cycle; and electr... Read More »
