ATP has 3 phosphate groups. Their bonds are unstable and so have a low activation energy, which means they are easily broken. When they break by the addition of water during a hydrolysis reaction, they re...

Proteins are produced at the ribosome. Ribosomes dock to the rER membrane on translocons and peptide is inserted into the rER lumen coupled with ATP hydrolysis. The peptide folds into its tertiary structu...

1. Pacinian corpuscle is stimulated by pressure on the skin. 2) This opens stretch mediated sodium ion channels. 3) Sodium ions leak into the sensory nerve axon via facilitated diffusion thereby causin...
