1

What is the word equation for aerobic respiration?

Glucose + oxygen --> carbon dioxide + water

2

What are some life processes that require energy from respiration?

Muscle contraction
Protein synthesis
Control of body temperature in mammals

3

What is the symbol equation for aerobic respiration?

C6H12O6 + 6O2 --> 6CO2 + 6H2O

4

What is respiratory quotient?

It tells you whether someone is respiring aerobically or anaerobically

5

What is the equation for respiratory quotient?

RQ = carbon dioxide / oxygen used

6

What is ATP?

An energy source for many processes in cells and transports energy to where its needed

7

How can the rate of oxygen consumption be used as an estimate of metabolic rate?

When respiration rate increases both oxygen consumption and carbon dioxide production increases
Aerobic respiration requires oxygen

8

What is the metabolic rate?

The amount of energy being used

9

Why is the rate of respiration influenced by changes in temperature and pH?

Respiration is controlled by enzymes

10

Why do breathing and pulse rates increase during exercise?

When you do vigorous exercise your body needs to supply more oxygen to your muscles for aerobic respiration

11

Why does anaerobic respiration take place in addition to aerobic respiration?

When you do vigorous exercise your body cant supply enough oxygen to your muscles for aerobic respiration

12

What is the word equation for anaerobic respiration?

Glucose--> lactic acid

13

How is lactic acid removed during recovery?

-hard exercise causing lack of oxygen in cells
-the incomplete breakdown of glucose
-continued panting replacing oxygen allowing aerobic respiration
-increased heart rate ensuring that blood carries lactic acid away to the liver

14

What is respiration?

Respiration is a chemical reaction that takes place in the mitochondria. It is when glucose reacts with oxygen to produce carbon dioxide and energy is released

15

Describe an experiment to measure resting pulse rate and recovery time after exercise

-meaure heart rate
-jumping jacks for 1 minute
-measure heart rate again

16

Describe an experiment to measure resting pulse rate and recovery time after exercise

-meaure heart rate
-jumping jacks for 1 minute
-measure heart rate again
