Intro to cellular respiration

Trivia Time Get in groups of 2-3 (work with people

you usually do not work with) Take notes while we do this

Which part of a eukaryotic cell is involved in cellular respiration?

nucleus endoplasmic reticulum mitochondria

Which is not a by-product of cellular respiration?

ATP Water Glucose

In the presence of oxygen, the first stage of cellular respiration is ...

Glycolysis The citric acid cycle Electron transport

Define cellular respiration

Cell respiration is the controlled release of energy from organic compounds in cells to form ATP.

Overview of Cellular Respiration

In glycolysis, each glucose molecule is broken down to two molecules of …

acetyl coenzyme A pyruvate citric acid

Without oxygen, glycolysis allows cells to make small amounts of ATP through a process called ...

oxidative phosphorylation• Another way to make ATP

electron transport fermentation

• There are two types of fermentation:• Lactic Acid fermentation (sore muscles)

• Alcohol fermentation

Upon entering the mitochondria, pyruvic acid molecules are converted to _____ molecules to be used in the citric acid cycle

citric acid• A six carbon compound in the citric acid cycle

acetyl coenzyme A• An enzyme joined with two carbons (think of

Coenzyme A as an escort for carbon molecules into the citric acid cycle)

fumaric acid • An intermediary in the citric acid cycle which is used to

produce ATP. It can also be added to candy to make it taste sour and even be used to treat psoriasis.

In a eukaryotic cell, most of the ATP derived from glucose during cellular respiration is produced by ...

Glycolysis The citric acid cycle The electron transport chain

Glucose and _______ are consumed during cellular respiration.

carbon dioxide oxygen water

Most of the ATP produced by the electron transport chain is generated from the oxidative phosphorylation of NADH and ____ .

FADH2

FAD NAD+

flavin adenine dinucleotide

FAD can be reduced to FADH2

FAD can be reduced to FADH2
