Why do highly active cells have large amounts of mitochondria?

• It increases the amount of nutrients absorbed into the cell

• It increases the amount of ATP produced

• It decreases the amount of nutrients absorbed into the cell

• There is no significance to the large amounts of ATP will be produced

Define Glycolysis

• A process in which glucose (sugar) is partially broken down by cells in enzyme reactions that do not need oxygen.

• A process in which glucose (sugar) is not broken by cells in enzyme reactions and do need oxygen.

• A process in which glucose (sugar) is completely broken and cells in enzyme reactions need oxygen.

• A process in which glucose (sugar) is not broken and cells in enzyme reactions that does not need oxygen.
