Document Summary
The human body uses energy from atp for all its activities. Average human needs: 2200kcal of energy/day: 75% to maintain healthy body (mostly brain, 25% to power physical activity. Breathing supplies o2 for use in cellular respiration and removes. Exergonic process (transfers energy from the bond in glucose to form atp) Cellular respiration: produces up to 32 atp molecules from each glucose molecule and, captures only about 34% of the energy originally stored in glucose. Cells tap energy from electrons falling: from organic fuels to. The energy necessary for life is contained in the arrangement of electrons in. When the carbon-hydrogen bonds of glucose are broken, electrons are chemical bonds in organic molecules. transferred to oxygen: oxygen has a strong tendency to attract electrons, an electron loses potential energy when it falls to oxygen. The movement of electrons from one molecule to another is an oxidation- reduction reaction, or redox reaction. In a redox reaction: oxidation: loss of electrons.
