Question

practice it! which of the following are examples of ways cells get energy to maintain homeostasis?
photosynthesis

sweating

getting sick

using the bathroom

cellular respiration

energy and human life

Explanation:

• photosynthesis: Plants, algae, and some bacteria use photosynthesis ($\ce{6CO_2 + 6H_2O \xrightarrow[chlorophyll]{light} C_6H_{12}O_6 + 6O_2}$) to convert light energy into chemical energy (glucose) for cells to use, helping maintain homeostasis.
• cellular respiration: Cells (both plant and animal) perform cellular respiration ($\ce{C_6H_{12}O_6 + 6O_2

ightarrow 6CO_2 + 6H_2O + ATP}$) to break down glucose and release ATP (energy) needed for cellular processes to maintain homeostasis.

• sweating: Is a way to regulate body temperature (homeostasis - related but not an energy - getting method for cells).
• getting sick: Is a disruption of homeostasis, not a way to get energy.
• using the bathroom: Is for waste removal (homeostasis - related but not an energy - getting method for cells).

Answer:

photosynthesis, cellular respiration
