Unit 7: Cellular Respiration Flashcard

Front

What is the first step of cellular respiration?

Back

Glycolysis

Front

What do FADH₂ and NADH provide for the Electron Transport Chain (ETC)?

Back

Energy/electrons

Front

What is the relationship between exercise difficulty and oxygen uptake?

Back

Difficult exercise requires additional oxygen intake in order to generate extra ATP for muscles.

Front

At what level of exercise difficulty does oxygen uptake reach 3L/min?

Back

Approximately 225 watts.

Front

Which process in cellular respiration produces the most ATP?

Back

Electron Transport Chain

Front

Define cellular respiration.

Back

The process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is glycolysis?

Back

The first step of cellular respiration that breaks down glucose into pyruvate, producing a small amount of ATP.

Front

What is the Krebs Cycle?

Back

A series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetyl-CoA.

Front

What is the role of the Electron Transport Chain?

Back

To use electrons from NADH and FADH₂ to create a proton gradient that drives ATP synthesis.

Front

What is lactic acid fermentation?

Back

An anaerobic process that converts glucose into energy and produces lactic acid as a byproduct.
