$$C_6H_12O_6 + 6O_2 \rightarrow 6CO_2 + 6H_2O + \textEnergy (ATP)$$ Cell Energy Gizmo Answer Key

How do animals get the carbon they need for growth? Answer: By eating plants (or other animals) that contain glucose/organic carbon.

Answer: In the chloroplast .

The Gizmo illustrates that the two processes are a continuous cycle:

The Gizmo simulates (in chloroplasts) and cellular respiration (in mitochondria). Mitochondria | Term | Correct Definition | |

Answer: Oxygen levels increase because more photosynthesis occurs.

When looking for the "Cell Energy Gizmo Answer Key," ensure that the explanations for these prior knowledge questions focus on energy transfer, not just simple definitions. | | Chlorophyll | The green pigment in

Answer: No. Photosynthesis requires light energy. In the dark, the oxygen production rate drops to zero.
