Which part of ATP and ADP is the most important for the storage and release of energy?

• Adenine

• Ribose

• Phosphate groups

Which form of energy is good at storing energy? Which form of energy is good at releasing/transferring energy?

• ADP is good at storing energy; ATP is good at transferring energy

• ATP is good at storing energy; ADP is good at transferring energy

• Both ATP and ADP are good at storing and releasing energy

• Both DNA and RNA are good at storing and releasing energy

How does ATP become ADP?

• A phosphate group is added to the molecule

• The bond between the 2nd and 3rd phosphate groups is broken

What is photosynthesis?

• „The process in which autotrophs use energy from sunlight to produce high-energy carbohydrates that can be used as food

• The process in which heterotrophs use energy from sunlight to produce high-energy carbohydrates that can be used as food

• The process in which autotrophs use energy from breaking chemical bonds to produce high-energy carbohydrates that can be used as food

• The process in which heterotrophs use energy from breaking chemical bonds to produce high-energy carbohydrates that can be used as food

What are pigments?
