KC#2 Cellular Respiration & Carbon Cycle Flashcard Review

Front

What is the carbon cycle?

Back

The carbon cycle is the process by which carbon is exchanged among the atmosphere, land, water, and living organisms. It involves processes like photosynthesis, respiration, decomposition, and combustion.

Front

Where is carbon NOT stored in the carbon cycle?

Back

Sunlight.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy, using carbon dioxide and water to produce glucose and oxygen.

Front

What is the chemical equation for aerobic cellular respiration?

Back

C6H12O6 + O2 --> CO2 + H2O + ATP.

Front

How does CO2 concentration affect global temperature?

Back

As CO2 concentration increases, average global temperature increases.

Front

What is aerobic respiration?

Back

Aerobic respiration is a process in which cells use oxygen to break down glucose, producing energy (ATP), carbon dioxide, and water.

Front

What is the role of oxygen in aerobic respiration?

Back

Oxygen is used to help convert glucose into energy (ATP) during aerobic respiration.

Front

What are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of ancient plants and animals, primarily composed of carbon, and are used as energy sources.

Front

What is the significance of decomposers in the carbon cycle?

Back

Decomposers break down dead organic matter, returning carbon to the soil and atmosphere, thus playing a crucial role in recycling nutrients.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of Earth's surface due to the trapping of heat by greenhouse gases like CO2, which increases with higher carbon emissions.
