2.2 Cell Energetics Flashcard

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

Which organisms perform cellular respiration?

Back

Both autotrophs and heterotrophs perform cellular respiration.

Front

What is the equation for cellular respiration?

Back

The equation is: oxygen + sugar -> carbon dioxide + water + Energy.

Front

What is ATP?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, storing and providing energy for various cellular processes.

Front

How do plants absorb water?

Back

Plants absorb water through their roots, which then travels up the stem to the leaves.

Front

What is the role of glucose in cellular respiration?

Back

Glucose is a primary fuel source that is broken down during cellular respiration to produce ATP.

Front

What is the difference between autotrophs and heterotrophs?

Back

Autotrophs produce their own food (e.g., plants), while heterotrophs consume other organisms for energy (e.g., animals).

Front

What is fermentation?

Back

Fermentation is an anaerobic process that allows cells to produce energy without oxygen, often resulting in byproducts like alcohol or lactic acid.

Front

What is the main purpose of cellular respiration?

Back

The main purpose of cellular respiration is to convert biochemical energy from nutrients into ATP.

Front

What is the byproduct of cellular respiration?

Back

The byproducts of cellular respiration are carbon dioxide and water.
