Oxidative phosphorylation relies on the hydrogen ion concentration gradient generated and maintained by the electron transport chain.
Hydrogen ions are actively transported out of the mitochondrial matrix.
Hydrogen ion concentration is higher in the intermembrane space than in the mitochondrial matrix.
Secondary structures are dependent upon hydrogen bonding. The two main types of secondary structure are the a-helix and the B-sheet. The a-helix is a right-handed coiled strand.
The statement is true. DNA replication process happen during the cell cycle.
<span>Amylase needs an optimum pH for its activity. It is in the range of 6-7. Below or above pH will denature this enzyme. The pH level is optimum for this enzyme in the mouth and hence it catalyses the break down of sugar. The pH level of stomach is lower than its optimum level duet to the activity of gastric acid. Hence the enzyme becomes inactive in the stomach.</span>
