What is aerobic respiration?

Back

Aerobic respiration is a metabolic process that requires oxygen to convert glucose into energy (ATP), producing carbon dioxide and water as byproducts.

What is anaerobic respiration?

Back

Anaerobic respiration is a metabolic process that occurs without oxygen, converting glucose into energy (ATP) and producing byproducts such as lactic acid or ethanol.

Front

How does aerobic respiration differ from anaerobic respiration in terms of ATP production?

Back

Aerobic respiration produces more ATP than anaerobic respiration.

Front

What role do autotrophs play in the carbon cycle?

Back

Autotrophs use carbon dioxide to produce glucose through photosynthesis, playing a crucial role in the carbon cycle.

Front

What happens to a red blood cell in a hypertonic solution?

Back

The red blood cell will shrink from losing water molecules.

Front

What is the significance of gas exchange in a closed ecosystem like a terrarium?

Back

Gas exchange is essential for maintaining the carbon cycle, allowing organisms to take in oxygen and release carbon dioxide.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is the effect of placing a freshwater plant in saltwater?

Back

The cells of the freshwater plant will shrink because water will move out of them due to osmosis.

Front

What are the byproducts of aerobic respiration?

Back

The byproducts of aerobic respiration are carbon dioxide and water.

Front

What is the function of decomposers in the carbon cycle?

Back

Decomposers break down dead organic matter, returning carbon to the soil and atmosphere, thus facilitating the carbon cycle.
