Respiration

What is metabolism

All the chemical reactions happening in your body building up and breaking down molecules.

What is respiration

The chemical reaction that causes the release of energy from glucose as it is broken down.

What is the word equation for aerobic respiration

Glucose + oxygen → water + carbon dioxide

What is the balanced symbol equation for aerobic respiration

C6H12O6 + 6O2 → 6H2O + 6CO2

What is the word equation for anaerobic respiration

Glucose → lactic acid (+small amount of energy)

What is the symbol equation for anaerobic respiration

C6H12O6 → 2C3H6O3

List the three main adaptations of the alveoli

large surface area, thin walls, good blood supply

Why is less energy released during anaerobic respiration

The breakdown of glucose is incomplete

What does the body use if it does not have enough glucose

Glycogen

What is oxygen debt

The amount of extra oxygen needed to break down the lactic acid

What two products are produced with fermentation

Bread , alcoholic drinks

What is your heart rate

The number of beats in one minute

What is your breathing rate

The number of breaths taken in one minute

What is breath volume

The volume of air taken in by one breath

What do blood vessels do

Carry blood to cells

Name the gas which is excreted through the alveoli

Carbon dioxide

What is the purpose of respiration

To release energy

What is meant by metabolic rate

The rate at which metabolic reactions are happening in your body
