Which of the following is not part of the process known as oxidative phosphorylation?(a) Molecular oxygen serves as a final electron acceptor.(b) FADH2 and NADH become oxidized as they transfer a pair of electrons to the electron-transport chain.(c) The electron carriers in the electron-transport chain toggle between reduced and oxidized states as electrons are passed along.(d) ATP molecules are produced in the cytosol as glucose is converted into pyruvate.

Look at the potential energy diagram for a chemical reaction. which statement correctly describes the energy changes that occur in the forward reaction?

There is a theory that indicates that dinosaurs became extinct when about 65 million years ago, a large asteroid hit the earth surface. dust caused by this collision blocked the sunlight reaching the earth's surface and many forms of life became extinct due to the cold. fearing this threat, how large the radius of an asteroid should you be looking for if the dangerous asteroid size is approximately the same as the one that killed the dinosaurs? available data suggests that about 18% of that asteroid's mass ended up as a dust spread evenly over earth after eventually settling out of the upper atmosphere. about 0.0180 g/cm^2 of dust, which is chemically different than the earth's rock, covered the earth's surface. typical asteroids have a density of about 1.9 g/cm^3. now that we know the size of the asteroid, how much energy was released during impact, assuming all of it was just the kinetic energy of the asteroid right before the impact?
