mitochondria有chemical reaction

Question

點解 mitochondria involved in metabolic activity??

mitochondria 只係release energy， 都無chemcial reaction。

雖然repiration 係metabolic activity, 但係mitochondrion 只係for 「 releasing 」that energy. mitochondrion 都無any chemical reaction

更新:

is that mitochondrion needs chemcal reaction to break down something before releasing energy in the mitochondrion cells?

mitochondrion is for making and storing ATP(adnine triphosphate), which is a chemical with a high energy bonding.

ATP is formed by ADP(adnine diphosphate) in the following reaction:

ADP + phosphrate + energy(from breaking glucose, lipids, etc) → ATP

When the cell needs energy, ATP is broken down into ADP, phosphrate and release the energy to the cell.

The whole reaction is carried in the mitochondrion.

The breaking down of glucose, lipids is also carried out in the mitochondrion
