Aerobic respiration

A process in which energy is released from food (glucose)

1

Energy is .... Not ....

Released
Produced

2

What is the word equation for aerobic respiration

Glucose + oxygen --> carbon dioxide + water + energy

3

What is the balanced symbol equation for aerobic respiration

C(6)H(12)O(6) + 6O(2) --> 6CO(2) + 6H(2)O + energy

4

Describe respiration in cells

Respiration occurs in the mitochondria which have enzymes

5

Effects of exercise on the body

-breathing rate increases
-depth of breath increases (as more oxygen for respiration to make glucose to function muscles)
-heart rate increases
-feeling hotter (same energy converted to heat)

6

Describe some changes that occur after exercising regularly

-amount of blood pumped out of the heart during each beat (cm[3]) increases
-heart volume increases
-breathing rate (number of breaths per min) decreases
-pulse rate (beats per min) decreases

7

Anaerobic respiration

-in the absence of O2 respiration can still happen
-this is called anaerobic respiration (without oxygen)

8

Word equation for anaerobic respiration

Glucose --> lactic acid + energy

9

Which type of respiration is more efficient

Aerobic respiration is 16x more efficient

10

Balanced symbol equation for anaerobic respiration

C(6)H(12)O(6) --> 2C(3)H(6)O(3) + energy

11

Oxygen debt

The additional oxygen that must be taken into the body after vigorous exercise for the body to 'respire' the lactic acid made in anaerobic respiration

12

The word equation for breaking down lactic acid

Lactic acid + oxygen --> carbon dioxide + water

13

The balanced symbol equation for breaking down lactic acid

C(3)H(6)O(3) + 3O(2) --> 3CO(2) + 3H(2)O

14

Word equation for yeast aerobic respiration

Glucose + oxygen --> carbon dioxide + water

15

Balanced symbol equation for aerobic respiration in yeast

C(6)H(12)O(6) + 6O(2) --> 6CO(2) + 6H(2)O

16

Word equation for anaerobic respiration in yeast (=alcoholic fermentation)

Glucose --> ethanol + carbon dioxide

17

Balanced symbol equation for anaerobic respiration

C(6)H(12)O(6) --> 2C(2)H(5)OH + 2CO(2)
