Why do cells contain many mitochondria?
A
To store excess nutrients for the cell.
B
To increase the surface area for photosynthesis.
C
To produce more ATP through cellular respiration.
D
To facilitate the transport of proteins across the cell membrane.
검증된 단계별 안내1
Understand the role of mitochondria: Mitochondria are known as the powerhouses of the cell because they are responsible for producing ATP (adenosine triphosphate), the energy currency of the cell, through the process of cellular respiration.
Recognize the process of cellular respiration: Cellular respiration is a series of metabolic reactions that convert biochemical energy from nutrients into ATP. This process primarily occurs in the mitochondria.
Identify the need for multiple mitochondria: Cells that require a lot of energy, such as muscle cells, contain many mitochondria to meet their high energy demands by producing more ATP.
Differentiate from other functions: While mitochondria are crucial for ATP production, they are not involved in storing nutrients, photosynthesis, or directly facilitating protein transport across the cell membrane.
Conclude the reason for many mitochondria: The presence of many mitochondria in a cell is to maximize ATP production through cellular respiration, supporting the cell's energy needs efficiently.
