Aerobic Respiration Grade 7 Science

Vocabulary flashcards covering aerobic respiration concepts, equations, and respiratory adjustments based on energy needs.

Aerobic Respiration

A chemical process in which oxygen is used to make energy from carbohydrates (sugars).

Alternative Names for Aerobic Respiration

Aerobic metabolism, cell respiration, and oxidative metabolism.

ATP (Adenosine Triphosphate)

A molecule in which energy is stored in our bodies, which can then be used to provide energy to other parts of the cell.

Chemical Equation for Cellular Respiration

$$C_6H_{12}O_6 + 6O_2 \rightarrow 6CO_2 + 6H_2O + \text{energy (ATP)}$$

Word Equation for Cellular Respiration

$$\text{Glucose} + \text{Oxygen} \rightarrow \text{Carbon dioxide} + \text{Water} + \text{ATP}$$

Carbon Dioxide

A waste product produced during cellular respiration that must be expelled from the body.

Organization Levels of Multicellular Organisms

Cells make up tissues, tissues make up organs, organs make up organ systems, and organ systems make up multicellular organisms.

Respiration Adjustment During Exercise

Breathing rate increases because cells require a lot of energy, ensuring each cell gets more oxygen to produce more energy.

Respiration Adjustment During Sleep

Breathing rate decreases because energy requirements decrease, ensuring each cell gets just enough oxygen to produce the required energy and no more.
