Unit 7.1 Glycolysis Review

Unit 7.1 Glycolysis Review

Multiple Choice

In cellular respiration...

• Water and light energy are broken down to make energy

• Glucose and Oxygen are broken down to make energy

• Carbon Dioxide is used in the Calvin Cycle to make food

• Autotrophs make their own food with help from the byproducts heterotrophs

In cellular respiration, the equation is opposite what we learned last Unit in Photosynthesis. Glucose and Oxygen are broken down and Energy (ATP) is the main product of cellular respiration.

Multiple Choice

Cellular Respiration mainly occurs in the mitochondria. However, glycolysis occurs in the:

• Nucleus

• Lysosome

• Cell Membrane

• Cytoplasm

Note the "Cytosol" is another word for "Cytoplasm"

"Aerobic" means "air" must be present

You could have also answered "Oxygen" or "O₂" to be correct

Multiple Choice

In Glycolysis, Glucose is split into two separate molecules. These molecules have 3 Carbons each. What are they called?

• Glycolose

• Carbon Dioxide

• Pyruvate

• ATP/ADP

Simplified image of Glycolysis -->

• We start with Glucose, and in the presence of Oxygen it is broken down into Pyruvate (Pyruvic Acid)

• In that process, 2 ATP (energy!) and 2 NADH are produced

Multiple Choice

Which of the following has two electrons attached to it?

• NAD+

• NADH

Remember that NADH is our "fully charged battery" and carries 2 electrons to the next phase of Cellular Respiration

Add this to your Concept Map if you answered the last question incorrectly.

Multiple Choice

Oxygen is one requirement for Glycolysis to take place. Which of the following is the other REACTANT of Glycolysis?

• Glucose

• 2 ATP

• 2 Pyruvate

• 2 NADH
