Glycolysis Concepts and Processes

What does the word "glycolysis" mean in the process of cellular respiration?

• Making new cells

• Breaking down sugar

• Storing energy

• Building proteins

What is the main sugar molecule that is broken down during glycolysis?

• Fructose

• Sucrose

• Glucose

• Lactose

How many ATP energy units are used during the first part of glycolysis?

• 1 ATP

• 2 ATPs

• 4 ATPs

• 6 ATPs

After the investment phase, the 6-carbon glucose molecule is broken down into how many smaller carbon molecules?

• One 6-carbon molecule

• Two 3-carbon molecules

• Three 2-carbon molecules

• Six 1-carbon molecules

What is the main job of glycolysis in a cell?

• To make food for the cell.

• To break down sugar (glucose) into smaller parts.

• To build new proteins.

• To help the cell move.

When a sugar molecule (glucose) is broken down during glycolysis, what are the smaller pieces called?

• Water

• Oxygen

• Pyruvate

• Carbon dioxide

How many energy packets (ATP) does a cell get to keep after glycolysis, from one sugar molecule?

• 1

• 2

• 3

• 4

How many carbon atoms are in one molecule of glucose before it starts to break down in glycolysis?

• 3

• 6

• 9

• 12
