Organisms such as plants and animals need the constant production of ATP at the cellular level to maintain daily functions. What process allows for these organisms to produce ATP and and where does it take place in the cell
The process is cellular respiration and happens in the Mitochondria
The process is photosynthesis and happens in the Chloroplast
The process in cellular respiration and happens in the Golgi Apparatus

How is the energy released from ATP?
A phosphate is removed
A phosphate is added
An adenosine is added
An adenosine is removed
How is energy stored when ADP is converted to ATP?
A phosphate is added to ADP
A phosphate is added to ATP

Identify the correct chemical reaction for photosynthesis
6CO2 + 6H2O + light energy → C6H12O6 + 6O2
Light energy+ C6H12O6→ 6CO2 + 6H2O
6CO2 + 6H2O→ 6CO2 + 6H2O + light energy
C6H12O6 + 6O2 → 6CO2 + 6H2O + light energy
Identify the correct chemical reaction for cellular respiration.
ATP+ C6H12O6→ 6CO2 + 6H2O
C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP
6CO2 + 6H2O + ATP → C6H12O6 + 6O2
6CO2 + 6H2O→ 6CO2 + 6H2O +ATP
In the diagram below, what products would the rabbit produce?
Rabbits perform cellular respiration and would produce CO2 ,H20 and and that is it
Rabbits perform cellular respiration and would produce C6H12O6 and energy as a product
Rabbits perform photosynthesis and would produce C6H12O6 and O2 as a product
Rabbits perform cellular respiration and would produce CO2 ,H20 and energy as a product
Where does photosynthesis occur?
In the chloroplast
In the nucleus
In the mitochondria
In the prokaryote
