Explanation:The primary function of the respiratory system is to deliver oxygen to the cells of the body's tissues and remove carbon dioxide, a cell waste product. The main structures of the human respiratory system are the nasal cavity, the trachea, and lungs
Answer:
transport of protons (H+) from low concentration in the mitochondrial matrix to high concentration in the mitochondrial intermembrane space
Explanation:
atpase pump can also be called atp synthase. this enzyme catalyses atp formation from adenosine diphosphate and phosphate. it has f1, stalk and f0 components. 3 positive hydrogen ions go through to make 1 adenosine triphosphate molecule. oxidative phosphorylation has to do with the loss of electrons. there would be electrons loss from NADH to FADH2. Cytochromes carries them through different series of transferases from I to IV and while on this positive hydrogen ions are released into mitochondrial matrix
positive hydrogen ions are moved back to lumen through adenosine triphosphate channels. a process called chemiosmosis. the pro
Answer:
A.
Explanation:
Older fossils tend to lay in the lower levels of the ground. The further up the fossils are, the more likely you are to find something that looks like today. Think of it as stacking papers with different drawings on them from different ages. Oldest goes on the bottom, newest goes on the top. The older layer stands as more of a foundation point while newer layers are around where we are now.
