Protons are pumped across the mitochondrial inner membrane as electrons are transferred through the mitochondrial electron transport chain. which of the following statements about proton pumping are correct? choose one or more: a. protons are pumped into the matrix of the mitochondria. b.the nadh dehydrogenase, cytochrome b-c1, and cytochrome oxidase complexes all pump protons across the membrane. c.the ph inside the mitochondrial matrix is higher than in the intermembrane space. d.the mitochondria use the proton gradient to synthesize atp.

question: which statement best describes the different properties of metals?

answer: they are shiny and bend without breaking.

since metals have certain characteristics properties, they include the following: they are ductile, malleable, shiny, hard, lustrous, flexible and they are good conductor of heat and electricity. so therefore, metals are not dull and they are not non-flexible as listed. instead, they are shiny and flexible.

hope this , have a good day. c;

emerging idea only occurs as a raw idea that could appear out of nowhere. meanwhile, to reach scientific consensus , that idea must be structured and tested over and over again through various experiments. the scientific consensus transforms the raw idea into idea that is more reliable through the process of scientific elimination.
