Miller and Levine Chapter 10.1-10.2

Front

What is ATP and its role in cellular respiration?

Back

ATP (adenosine triphosphate) is the primary energy carrier in cells, produced during cellular respiration to provide energy for various cellular processes.

Front

What is the process of ATP synthesis in the electron transport chain?

Back

The high concentration of hydrogen ions in the intermembrane space allows them to diffuse across the membrane into the matrix, driving ATP synthesis.

Front

How many molecules of ATP are produced during glycolysis?

Back

Glycolysis yields 2 molecules of ATP.

Front

What is the primary function of glycolysis in cellular respiration?

Back

Glycolysis breaks down glucose into pyruvate, producing ATP and NADH in the process.

Front

Where does the Krebs cycle occur in eukaryotic cells?

Back

The Krebs cycle occurs in the matrix of the mitochondria.

Front

What is the main difference between prokaryotic and eukaryotic cells regarding the electron transport chain?

Back

In prokaryotes, the electron transport chain is located in the cell membrane, while in eukaryotes, it is located in the inner mitochondrial membrane.

Front

What is the role of NAD+ in cellular respiration?

Back

NAD+ acts as an electron carrier, accepting electrons during glycolysis and the Krebs cycle to form NADH.

Front

What is the significance of the intermembrane space in mitochondria?

Back

The intermembrane space is crucial for creating a proton gradient used to drive ATP synthesis during oxidative phosphorylation.

Front

What are the end products of the Krebs cycle?

Back

The end products of the Krebs cycle include carbon dioxide, ATP, NADH, and FADH2.

Front

What is oxidative phosphorylation?

Back

Oxidative phosphorylation is the process of ATP production that occurs in the electron transport chain, using energy from electrons to pump protons and create a gradient.
