Understanding Mitochondria

The video explains the role of mitochondria as the powerhouse of the cell, found in all eukaryotic cells including plants, animals, fungi, and protists. Mitochondria can change shape and move within the cell, and they reproduce by growing and dividing when more energy is needed. During exercise, the number of mitochondria in muscle cells increases, enhancing energy availability.

What is the primary role of mitochondria in the cell?

• To produce energy

• To synthesize proteins

• To transport nutrients

• To store genetic information

In which types of cells are mitochondria found?

• In all eukaryotic cells

• In prokaryotic cells

• Only in plant cells

• Only in animal cells

How do mitochondria respond when a cell requires more energy?

• They release stored nutrients

• They shrink and become inactive

• They fuse with other organelles

• They grow larger and divide

What happens to mitochondria in muscle cells during exercise?

• They decrease in number

• They move to the center of the cell

• They increase in number and move to the cell edges

• They become inactive

Why is the movement of mitochondria to the cell edges important during exercise?

• To prevent cell damage

• To reduce cell size

• To increase cell temperature

• To enhance energy availability for muscles
