Energy and Life 8.1 Quiz

Cells use a molecule called​ ​ (a)   to store and

release energy like a battery. The energy is stored in chemical bonds between​ ​ ​ ​​ (b)  

groups of the molecule, and the

energy is released when the chemical bonds are brok​en​

• ATP
• phosphate
• DNA
• RNA
• CMP
• Nucleotide
• oxygen

Energy is released from an ATP molecule for cellular processes when it 

• has a phosphate group removed
• stores and extra phosphate group
• converts a phosphate group to ADP
• produces a sugar molecule

Why are mushrooms considered heterotrophs?

• Mushrooms make their own food
• Mushrooms feed through photosynthesis
• Mushrooms trap and eat small flying insects
• Mushrooms feed by absorbing decomposing nutrients from organisms

What is the difference between ATP and ADP?

• ADP powers movement, while ATP does not
• ATP has three phosphates; ADP has two
• ATP contains adenine and ribose, while ADP does not
• ATP has less energy than ADP

One way cells use the energy provided by ATP is to 

• carry out active transport
• carry out diffusion
• remove two phosphate groups
• carry out osmosis

Why do cells contain only a small amount of ATP?

• ATP cannot store large amounts of energy for a long time.
• ATP releases energy too quickly.
• ATP cannot carry out active transport.
  
• ATP has only two phosphate groups
