3.2 Bioenergetics

Question 1

Three steps of Cellular Respiration

Answer 1

1. ) Glycolysis - breaking glucose into two molecules of G3P
2. ) Kreb’s Cycle - making electron carriers in the continued breakdown
3. ) e-transport chain - free E from electrons is used to help make ATP

Question 2

Glucose will be broken apart into 2 molecules of G3P. Each molecule of G3P I’ll then be converted to a molecule of Pyruvate. At the end the cell will have two Pyruvate molecules that can be put into the Mitochondria is oxygen is present and it’s a eukaryotic cell.

Answer 2

Glycolysis

Question 3

E Investment Phase

Answer 3

Glucose is broken down into two molecules of G3P. To break it in half requires 2 ATP to be used.

Question 4

E Payoff Phase

Answer 4

Two molecules of G3P will then be converted to 2 molecules of Pyruvate. There will be two ATP and one NADH per molecule. Occurs with or without O2 present. All organisms do it as it occurs in the cytoplasm on a cell

Question 5

“With oxygen”

Answer 5

Aerobic

Question 6

Pyruvate is converted to Acetyl Coenzyme A to get to the inner Mitochondrial space where Kreb’s Cycle occurs

Answer 6

Pyruvate Conversion

Question 7

Inner mitochondrial space

Answer 7

Where Kreb’s Cycle occurs

Question 8

Makes Electron Carriers by tearing of hydrogens and attaching them to Electron carriers

Answer 8

Kreb’s Cycle

Question 9

The process of releasing energy contained in organic molecules to do work

Answer 9

Cellular Respiration
