Soc18 Aerobic,Anaerobic Exercise And Energy Sources

Question 1

What is glucose?

Answer 1

A major source of energy for most cells in the body

Question 2

What is Aerobic Respiration?

Answer 2

The process of releasing energy from glucose, using oxygen

Question 3

What is Anaerobic Respiration

Answer 3

The process of releasing energy from glucose,without oxygen

Question 4

What is Aerobic Exercise?

Answer 4

working at a moderate intensity allowing the body time to utilise oxygen for energy production and to work for a continuous period, e.g. long-distance events.

Question 5

What is Lactic Acid

a colourless acid produced in muscle tissues during strenuous exercise when the body is exercising anaerobically at high intensity.

Question 6

Question 9

What is meant by Anaerobic ?

Answer 9

This means the absence of oxygen

Question 10

Word equation of Aerobic Activity?

Answer 10

This is

Glucose + Oxygen —> Water + Carbon Dioxide + Energy

Question 11

Word equation for Anaerobic Exercise

Answer 11

Glucose —> Lactic Acid + Energy

Question 12

2 Main sources of Energy

Answer 12

Carbohydrates
Fats

Question 13

Info card

Answer 13

Carbohydrats are the Main source of energy for both high and moderate intensity
Fats provide only moderate intensity

By moderate I mean Aerobic
High intesnity is Anaerobic

Question 14

Information about Fats

Answer 14

• Fats usually provide most of the body’s energy needs

• When you eat fat it is broken down into fatty acids, which are absorbed into your blood and delivered to your cells

• Any fatty acids that are not needed straight away can be stored in fat cells

• Fats are found in butter, margarine and cooking oils, as well as in foods such as bacon, cheese, fish and nuts

• Your daily intake of fats should be no more than 30% of your total diet

Question 15

Information About Carbohydrates

Answer 15

• Your body’s cells uses carbohydrates more easily than fat

• Carbohydrates can only be stored in small amounts - enough to last a day or two - so your body tends to use them first for energy

• When you eat carbohydrates, they are broken down into glucose or glycogen, which can be absorbed through the walls of your small intestine and into the blood

• Glucose will pass into the blood, be transported to the liver and then circulated around the body

• Once your cells have used as much glucose as they need, some of the excess is stored in the liver, ready to be distributed if your blood glucose levels get too low.

• The rest can be turned into fat for long term storage

Question 16

The 2 Types of Carbohydrates

Answer 16

Complex and Simple Carbohydrates

Question 17

Info About Complex Carbohydrates

Answer 17

• Complex carbohydrates for example starch are found in natural foods such as brown rice, wholemeal bread and wholemeal pasta

• Foods of this type help to provide slow releasing and long lasting energy for exercise and should form about half of your daily intake

Question 18

Info about Simple Carbohydrates

Answer 18

• Simple carbohydrates are stored in their natural form in fruit and vegetables, and in their refined form in biscuits, cakes and chocolates.

• They provide a quick fix of of energy. For example, eating a banana at half time of a football match.
