Biology Chapter 9 Study Guide

Calorie
Measure of heat energy in food; equivalent to 1000 calories
Aerobic
Process that requires oxygen
Anaerobic
Process that doesn’t require oxgen
Glycolysis
First set of reactions in a celular respiration in which a molecule of glucose is broken into two molecules of pyruvic acid.
Krebs Cycle
Second set of cellular respiration in which pyruvic acid is broken down into carbon dioxide in a series of energy extracting reactions.
Fermentation
Process by which cells release energy in the absence of oxygen.
Name three phases of cellular respiration.
1. Glycolysis
2. Krebs Cycle
3. Electron Transport Chain
In cellular respiration what causes energy to be released?
Chemical bonds are broken.
In which organelle does cellular respiration take place?
Mitochondria
List 2 things that cellular respiration needs.
1. Carbohydrates
2. Oxygen
List 3 things cellular respiration produces.
1. Water
2. Carbon Dioxide
3. Energy
Write out the cellular respiration equation. Write it first in chemical formula and word form.
6O2+C6H12O6–>6CO2+6H2O+Energy
Oxygen+Carbohydrates–>Carbon Dioxide+Water+Energy
At the end of the kreb cycle, how many ATP’s are produced?
2
Glycolysis literally means what?
Sugar breaking
In glycolysis there is a transformation of 2 compounds, what are they? (Not sure about this one)
Pryuvic Acid and Glucose
What is the main difference between aerobic and anaerobic?
Aerobic requires oxygen and anaerobic doesn’t.
In the Krebs cycle. pyruvic acid molecules are broken down into what?
Carbon Dioxide
The Krebs cycle produces four types of products. Name those four products.
1. NADH
2. Carbon Dioxide
3. 2 ATP Molecules
4. 4 Carbon Molecules
At the end of the Electron transport phase of cellular respiration how many ATP’s are produced?
3
Explain electron transport phase of cellular respiration.
Uses high energy electrons from glycolysis and krebs cycle to convert ADP to ATP.
List the two types of fermentation and write their equations below.
Alcoholic- Pyruvic acid+NADH–>Alcohol+CO2+NAD+
Lactic Acid Fermentation- Pyruvic Acid+NADH–>Lactic Acid+NAD+
In glycolysis, glucose is transformed into 2 molecules of what?
Pyruvic Acid
