Enzymes are biological catalysts that speed up chemical reactions by providing an alternative reaction pathway with lower activation energy.
Reduced NADP is used to reduce GP to TP. The ATP provides the energy needed for the reduction of the aforementioned reaction. It also provides a phosphate ion to regenerate RuBP from TP.
The Bohr shift should be explained using the relative affinities of haemoglobin to carbon dioxide and oxygen due to changes in pH level. When pCO2 is high in cells (i.e in muscle cells when one is exercis...
A pain stimulus, for example, pressure from a pin, is sensed by a receptor, for example, pacinian corpuscle in the skin of the fingertip.This causes a change in shape of the receptor, so sodium ions diffu...
A first messenger is a hormone which binds to a receptor on the plasma membrane of a cell and causes a change to happen inside the cell
