level phosphorylation? Oxidative phosphorylation is a metabolic pathway that uses energy released by the oxidation of nutrients to produce ATP. Oxidative phosphorylation uses the electrochemical gradient‚ set up by the oxidation of nutrients‚ of protons across the inner mitochondrial membrane to generate ATP from ADP. During oxidative phosphorylation‚ electrons are transferred from electron donors to electron acceptors such as oxygen‚ in redox reactions of the electron transport chain. These redox

to shield astronauts from the harmful effects of radiation. Hydrogen is a great form of radiation shielding because it absorbs the particles well. Hydrogen is normally found as a single electron and proton‚ causing it to be a great radiation shield‚ due to the similar size of hydrogen and the protons and neutrons from radiation. Hydrogen can be extracted from the water ice found in the north and south poles on Mars. The element would be extracted through the process of electrolysis‚ where an electric

named after the Greek God Prometheus. It is not naturally occurring‚ but can survive outside of a lab. Promethium has an atomic number of 61‚ which is the number of protons. Its atomic mass‚ protons+neutrons‚ is 145u. It is an isotope. This means that it has a different number of neutrons (84) than the number of electrons and protons (61). Every element changes states of matter at different temperatures. Promethium melts at 1042.0°C (1315 Kelvin)‚ boils at 3000.0°C (3273 Kelvin)‚ and freezes at 931

TOPIC 3.7 + 8.1: CELL RESPIRATION 3.7.1 Define cell respiration. Cell respiration is the controlled release of energy from organic compounds in cells to form ATP (adenosine triphosphates). 3.7.2 State that‚ in cell respiration‚ glucose in the cytoplasm is broken down by glycolysis into pyruvate‚ with a small yield of ATP. Glycolysis in cytoplasm: Glucose 2 pyruvates + small amount of ATP (does not use oxygen) 3.7.3 Explain that‚ during anaerobic cell respiration‚ pyruvate can be
