Bio-Clemical reactions talking Place in every Cell organelles ​

Each of these organelles performs a specific function critical to the cell's survival. For example, biochemical reactions in a cell's mitochondria transfer energy from fatty acids and pyruvate molecules into an energy-rich molecule called adenosine triphosphate (ATP).

Explanation:
