Most of the metabolic activity in a cell occurs in the mitochondrion. This organelle is responsible for the generation of ATP through a process known as oxidative phosphorylation. More »

Regulation of metabolic pathways is accomplished through the control of enzymatic activities, explains Collin College. The cell accomplishes this by either altering a pre-existing enzyme's activity or changing the availa... More »

A good metabolic rate balances the intake of diet by an individual with his total daily energy expenditure. The TDEE, or maintenance level, represents normal daily activities and physical exercise. The maintenance level ... More »

The organelle that provides energy for the cell is mitochondrion. While mitochondria are the primary source of energy in eukaryotic cells, cells can still derive a small amount of energy from other processes like glycoly... More »

Most of the activity of the electron transport chain occurs in a cell's mitochondrial inner membrane. This is where the electron transport chain gets the proteins it needs to function properly. More »

The function of the nucleus in the plant cell is to store the plant's DNA and control the activity of the cell through protein synthesis. The nucleus is enclosed by the nuclear membrane, which has pores for the passage o... More »

Dr. William H. Heidcamp, a professor in the Biology Department at Gustavus Adolphus College, explains that cell differentiation occurs when the structure and function of cells change within a certain period. The formatio... More »
