ATP = energy for the cell!!!!

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

• DNA
• lipids
• ATP
• ribosomes

The sodium-potassium pump in a cell membrane moves particles from an area of low concentration to an area of high concentration. What directly supplies the energy for the sodium-potassium pump?

• amino acids
• ATP
• DNA
• fatty acids

Scientists studying a certain species of bacteria hypothesize that these bacteria use active transport to take in sugar. Which of the following best supports this hypothesis?

• Sugar intake rate increases as the use of ATP increases
• Sugar intake rate increases as the temperature increases.
• Sugar intake rate increases as the number of ribosomes inside the bacteria increases.
• Sugar intake rate increases as the concentration of sugar outside the bacteria increases.

In a cell, a phosphate group is added to ADP to form ATP. Which of the following best describes the importance of the formation of ATP?

• A. It connects amino acids.
• B. It provides energy for the cell.
• C. It creates new polysaccharides.
• D. It catalyzes chemical reactions.
