The inner membrane of the mitochondria consists of a series of folds. How might this be advantageous to the cell?

• it increases surface area for energy production

• it allows efficient conversion of light to ATP energy

• it reduces the need for transport proteins

• it creates a specialized compartment for lipid storage

Why must DNA replication have to occur before a cell can divide by mitosis?

• to maintain the same number of chromosomes in the daughter cells as in the parent cell

• to cause one of the cells produced to have double the number of chromosomes as the parent cell

• to cause all of the cells produced to have half the number of chromosomes as the parent cell

• to allow crossing over to occur in each of the cells produced

How are mitosis and meiosis similar?

• both have two cell divisions

• both require DNA replication

• both produce gametes

• both involve crossing over

Salivary amylase is an enzyme in humans that breaks down starches. What substance would humans have difficulty digesting without this enzyme?

• lipids

• nucleic acids

• proteins

• carbohydrates

A contractile vacuole helps protists eliminate excess liquid. This is a“pumping" process that reduces pressure inside the cell and prevents the cell from bursting. What is most likely the source of energy for this process?

• DNA

• ATP

• lipids

• ribosomes
