question

Calorie
answer

Measure of heat energy in food; equivalent to 1000 calories
question

Aerobic
answer

Process that requires oxygen
question

Anaerobic
answer

Process that doesn’t require oxgen
question

Glycolysis
answer

First set of reactions in a celular respiration in which a molecule of glucose is broken into two molecules of pyruvic acid.
question

Krebs Cycle
answer

Second set of cellular respiration in which pyruvic acid is broken down into carbon dioxide in a series of energy extracting reactions.
question

Fermentation
answer

Process by which cells release energy in the absence of oxygen.
question

Name three phases of cellular respiration.
answer

1. Glycolysis 2. Krebs Cycle 3. Electron Transport Chain
question

In cellular respiration what causes energy to be released?
answer

Chemical bonds are broken.
question

In which organelle does cellular respiration take place?
answer

Mitochondria
question

List 2 things that cellular respiration needs.
answer

1. Carbohydrates 2. Oxygen
question

List 3 things cellular respiration produces.
answer

1. Water 2. Carbon Dioxide 3. Energy
question

Write out the cellular respiration equation. Write it first in chemical formula and word form.
answer

6O2+C6H12O6–>6CO2+6H2O+Energy Oxygen+Carbohydrates–>Carbon Dioxide+Water+Energy
question

At the end of the kreb cycle, how many ATP’s are produced?
answer

2
question

Glycolysis literally means what?
answer

Sugar breaking
question

In glycolysis there is a transformation of 2 compounds, what are they? (Not sure about this one)
answer

Pryuvic Acid and Glucose
question

What is the main difference between aerobic and anaerobic?
answer

Aerobic requires oxygen and anaerobic doesn’t.
question

In the Krebs cycle. pyruvic acid molecules are broken down into what?
answer

Carbon Dioxide
question

The Krebs cycle produces four types of products. Name those four products.
answer

1. NADH 2. Carbon Dioxide 3. 2 ATP Molecules 4. 4 Carbon Molecules
question

At the end of the Electron transport phase of cellular respiration how many ATP’s are produced?
answer

3
question

Explain electron transport phase of cellular respiration.
answer

Uses high energy electrons from glycolysis and krebs cycle to convert ADP to ATP.
question

List the two types of fermentation and write their equations below.
answer

Alcoholic- Pyruvic acid+NADH–>Alcohol+CO2+NAD+ Lactic Acid Fermentation- Pyruvic Acid+NADH–>Lactic Acid+NAD+
question

In glycolysis, glucose is transformed into 2 molecules of what?
answer

Pyruvic Acid
