Respiration

Question 1

what is respiration

Answer 1

cell respiration is the controlled release of energy from organic compounds to produce ATP
- chemical reaction within all cells that produces energy

Question 2

types of respiration

Answer 2

aerobic and anerobic

Question 3

what is aerobic respiration

Answer 3

• normal, efficient pathway through which the body uses breathing to inhale oxygen, which combines with glucose to form ATP

Question 4

formula for aerobic respiration

Answer 4

glucose + oxygen -> carbon dioxide + water + energy

C6H12O6 + 6O2 -> 6C02 + 6H20 + 36ATP

Question 5

what is anaerobic respiration

Answer 5

when the body is getting no oxygen from breathing; cell creates energy just using glucose
- its inefficient

Question 6

formula for anaerobic respiration

Answer 6

GLUCOSE-> lactic acid + energy (ANIMALS)

Glucose -> alcohol (ethanol) + energy (PLANTS)

Question 7

fermentation

Answer 7

alternative name for anaerobic respiration
two types:
1. alcholic
2. lactic acid

Question 8

what is the first step in cell respiration

Answer 8

GLYCOSIS: glucose enters the cell and is modified slightly by enzymes, breaking bonds that create ATP which are needed to start respiration

Question 9

what is alcholic respiration

Answer 9

• glucose is taken fro the environment to create ethanol and ATP and carbon dioxide

Question 10

what is lactic acid fermentation

Answer 10

• lactic acid produced from glucose without oxygen needed

Question 11

glycosis

Answer 11

• takes place in the cytoplasm
• results in the net gain of two ATP molecules per glucose molecule
• results in the produciton of pyruvate molecules

Question 12

what is pyruvate

Answer 12

• a modififed, broken down form of glucose which is broken down during glycolysis for respiration

Question 13

why does yeast cause bread to rise

Answer 13

the carbon dioxide produced from the anaerobic respiration causes the dough to rise; the ethanol evaporates
