Cellular Respiration Review

Define autotroph

Autotroph- organisms that manufacture their own energy

Define heterotroph

Heterotroph- consume their energy from other organisms

What are the products of Glycolysis

Pyruvate (contains stored energy from glucose), ATP, NADH

What is the oxidizing agent that is used to harvest high-energy electrons

NAD+

How is ATP made during chemiosmosis

H+ concentration on two sides of the mitochondria membrane

In substrate-level phosphorylation, how is ATP made

ATP is made by adding a phosphate group to ADP

Name the two types of fermentation

Alcoholic and Lactic acid Fermentation

What are the end products of one turn of the Krebs cycle

3 NADH, 1 ATP, 1 FADH2, 2 CO2

True/False. Glycolysis can occur with or without oxygen.

True

What is the difference in ATP production between NADH and FADH2

NADH passes its electrons to the first transmembrane complex in the ETC, more ATP made
FADH2 passes its electrons after the first transmembrane complex in the ETC, less ATP made

What is the final outcome for oxygen in cellular respiration

It accepts H+ and electrons to form water

During which process is ATP used in the process of cellular respiration

Glycolysis

What must happen to amino acids before they can be used in catabolic reactions

They must be deaminated

Where do the reactions of oxidation of Pyruvate, Krebs cycle and the electron transport chain
occur

Mitochondria

What occurs in muscles when oxygen is not present

Lactic acid fermentation

How many ATP’s are made during glycolysis

2 are used, 4 are produced for a net gain of 2 ATP’s

How many ATP’s are made from one glucose molecule in eukaryotes

30 ATP’s

What is entering and leaving at X and Y

Energy

Give the equation for the process occurring at A

6CO2 + 6H2O à C6H12O6 + 6O2

Give the equation for the process occurring at B

C6H12O6 + 6O2 à 6CO2 + 6H2O

Which process of cellular respiration is the oldest process

Glycolysis

Alcohol and Lactic fermentation are types of anaerobic respiration. What is missing for this to
occur

Oxygen
