DENDROLOGY

Detailed explanation-1: -Electron transport chain is the process which produces ATP in the final steps of cellular respiration, occurs in the inner mitochondrial membrane . The mitochondrion has an outer membrane and an inner membrane with folds called as cristae .

Detailed explanation-2: -The electron transport chain is a series of four protein complexes that couple redox reactions, creating an electrochemical gradient that leads to the creation of ATP in a complete system named oxidative phosphorylation. It occurs in mitochondria in both cellular respiration and photosynthesis.

Detailed explanation-3: -The energy available from combining molecular oxygen with the reactive electrons carried by NADH and FADH2 is harnessed by an electron-transport chain in the inner mitochondrial membrane called the respiratory chain.

Detailed explanation-4: -While most aerobic respiration (with oxygen) takes place in the cell’s mitochondria, and anaerobic respiration (without oxygen) takes place within the cell’s cytoplasm.
