Honors Cell Respiration

Front

What is the matrix in cellular respiration?

Back

The matrix is the innermost compartment of the mitochondria, where the Krebs cycle occurs and contains enzymes, mitochondrial DNA, and ribosomes.

Front

What is glycolysis?

Back

Glycolysis is the first step of cellular respiration that breaks down glucose into two molecules of pyruvate, producing a small amount of ATP and NADH.

Front

What gas is produced during the Krebs cycle?

Back

Carbon dioxide gas is released as a byproduct during the Krebs cycle.

Front

What are the three stages of cellular respiration in order?

Back

1. Glycolysis 2. Krebs Cycle 3. Electron Transport Chain

Front

What is the role of the inner membrane in mitochondria?

Back

The inner membrane contains proteins that carry out the electron transport chain and ATP synthesis.

Front

What is the function of cristae in mitochondria?

Back

Cristae are the folds of the inner membrane that increase the surface area for ATP production.

Front

What is aerobic respiration?

Back

Aerobic respiration is the process of producing cellular energy in the presence of oxygen, involving glycolysis, the Krebs cycle, and the electron transport chain.

Front

What is the electron transport chain?

Back

The electron transport chain is a series of protein complexes in the inner mitochondrial membrane that transfer electrons and pump protons to create a proton gradient for ATP synthesis.

Front

What is fermentation?

Back

Fermentation is an anaerobic process that allows for the production of energy without oxygen, resulting in products like lactic acid or ethanol.

Front

What is the significance of NADH in cellular respiration?

Back

NADH is an electron carrier that transports electrons to the electron transport chain, playing a crucial role in ATP production.
