Unit 3b: Ch. 10.1 (Intro Cell Resp) CONCEPT CHECK #1

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

What is the primary function of ATP in cells?

Back

ATP (adenosine triphosphate) serves as the main energy currency of the cell, providing energy for various cellular processes.

Front

Where does cellular respiration occur in eukaryotic cells?

Back

Cellular respiration occurs primarily in the mitochondria of eukaryotic cells.

Front

What are heterotrophs?

Back

Heterotrophs are organisms that cannot produce their own food and must consume other organisms for energy.

Front

What is the relationship between food calories and chemistry calories?

Back

1 food calorie is equal to 1000 chemistry calories.

Front

What are the three main stages of cellular respiration?

Back

The three main stages of cellular respiration are glycolysis, the Krebs cycle, and the electron transport chain.

Front

What is glycolysis?

Back

Glycolysis is the first stage of cellular respiration, where glucose is broken down into pyruvate, producing a small amount of ATP.

Front

What role do mitochondria play in cellular respiration?

Back

Mitochondria are the organelles where the Krebs cycle and electron transport chain occur, producing the majority of ATP.

Front

What is the Krebs cycle?

Back

The Krebs cycle, also known as the citric acid cycle, is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetyl-CoA.

Front

What is the electron transport chain?

Back

The electron transport chain is the final stage of cellular respiration, where electrons are transferred through a series of proteins, leading to the production of ATP.
