Concept Covered: Electron Transport Chain, The Mitochondria, Overview of Respiration, Krebs Cycle, Glycolysis

In glycolysis, high energy _____ are removed from glucose and passed to the electron carrier _____ to produce _____.

> Electrons > NAD+ >NADH

NAD+ is to respiration as _____ is to photosynthesis.

> NADP+

Summarize the events taking place during this last stage of respiration.

ATP is created and oxygen accepts electrons.

What organic compound produced in previous stages of respiration must be continually "fed" into the Krebs cycle?

Acetyl- Coenzyme A (CoA)

Is glycolysis aerobic or anaerobic? Where does it occur?

Anaerobic - Cytoplasm

What types of organisms will be able to carry out aerobic respiration inside the mitochondria?

Animals and Plants

Which organisms carry out cellular respiration?

Bacteria, Protists, Fungi, Plants, Animals

How is the function of NAD+ and NADP+ similar?

Both accept electrons.

Write an equation for respiration, indicating the reactants and the products.

C(6)H(12)O(6) + 6O(2) --> 6H(2)O + 6CO + ATP

What happens to each of the four compunds of the Krebs cycle?

CO(2) is moved along to Calvin cycle, ATP is used for cellular processes, NADH and FADH(2) are sent to the Electron Transport Chain (ETS) (ETC).

Four compounds are generated by and exported from the Krebs cycle. What are these four compounds?

CO(2), ATP, NADH, FADH(2)

Of the four compounds generated and exported from the Krebs cycle, how many are generated per acetate?

CO(2)= 2 ATP= 1 NADH= 3 FADH(2)= 1

Of the four compounds generated and exported from the Krebs cycle, how many are generated per glucose?

CO(2)= 4 ATP= 2 NADH= 6 FADH(2)= 2

What reaction occurs along the cristae membrane?

Enzymatic reactions of Cellular Respiration.

Define "Glycolysis".

Enzymes breaking down glucose for energy.

What is the purpose of NADH?

Helps make ATP, and acts as a shuttle for electrons.

Where do the Krebs cycle and the Electron Transport Chain (ETC) (ETS) occur in prokaryotic cells?

In the Cytosol.

What is the location of the Krebs cycle?

In the Matrix of the Mitochondria.

Where does the Electron Transport Chain (ETC) (ETS) occur?

In the Mitochondria

Describe the Cristae. What is their purpose?

Inner Membrane Space, Allows Electron Transport Chain (ETC) (ETS) to pass through.

What is the total number of NADP and FADH(2) (per molecule of glucose) reaching the Electron Transport Chain (ETC) (ETS)?

NADP= 4 FADH(2)= 1

Why is oxygen required for the final electron transport train?

Oxygen is the final electron acceptor at the end of the Electron Transport Chain (ETC) (ETS).

What reaction occurs in the Matrix?

Pyruvic Acid becomes Acytol.

Summarize ATP production in glycolysis.

Starts with two ATP and end with four.

Define the term "cellular respiration".

The process of generating energy for cells, and supplying them with ATP.

Describe the Matrix. What does it contain?

Tissue in cells, contains secreted glycoproteins.

What is the purpose of Electron Transport Chain (ETC) (ETS)?

To build many Hydrogen Ions (protons).

What is the purpose of the Krebs cycle?

To produce NADH and FADH(2), as well as removing oxygen from glucose.

There are two different types of cellular respiration. List and define them.

a.) Aerobic, with oxygen b.) Anaerobic, without oxygen

Respiration occurs in three main stages. List each stage and indicate whether it is anaerobic or aerobic. In what part of the cell does each stage occur?

a.) Glycosis - Anaerobic - Cytoplasm b.) Krebs Cycle / Citric Acid Cycle - Aerobic - Mitochondrian Matrix c.) Electron Transport Chain (ETC) (ETS) - Inner Membrane of Mitochondria / Cristae - Aerobic
