Cellular Respiration

Question 1

Where does Glycolysis take place?

Answer 1

Cytoplasm

Question 2

Where does the Krebs cycle (citric acid) take place?

Answer 2

Mitochondrial Matrix

Question 3

Where does the Electron Transport Chain take place?

Answer 3

Inner Mitochondrial Membrane

Question 4

What types of organisms perform cellular respiration

Answer 4

Producers
Consumers
Decomposers

Question 5

Glycolysis

Answer 5

1st step
~no oxygen is required for this step.
~glucose is converted to a more usable form called pyruvate.
~As a result, the net outcome from this process is approximately two pyruvate, 2 ATP energy molecules, and 2 NADH
~ NADH is a coenzyme that is used to transport electrons that will be used to make more ATP

Question 6

Electron transport chain

Answer 6

~takes electrons that were transferred from the NADH and FADH2 from the previous step, to protein complexes and electron carriers.
~There is a series of four organic protein molecules (protein gradient) found in the inner mitochondrial membrane.
~Electrons are passed from one member of the transport chain to another in a series of redox reactions (transferring electrons between chemical substances).
~net outcome of 34 ATP molecules.

Question 6

Krebs Cycle (Citric Acid Cycle)

Answer 6

~requires oxygen.
~The pyruvate from glycolysis is converted into different molecules and then gets further oxidized to create carbon dioxide.
~6 NADH, 2 FADH2, and 2 ATP energy molecules are made for the next step.

Question 7

Acetyl-CoA (acetyl coenzyme A)

Answer 7

~a molecule
~Its main function is to deliver the acetyl group (the converted form of pyruvate) to the citric acid cycle (Krebs cycle) to be oxidized for energy production.
