Which is the odd one out?
Collect some goggles and gather around Miss Walsh.... WHAT DOES RESPIRATION PRODUCE?

Homework: Over the next two weeks use the syllabus to create a full set of revision notes on topic 6 (Respiration)
Why is this reaction so important? Our cells need a constant supply of energy. Respiration takes place in ALL of our cells, ALL of the time.
Are these statements correct?
I pity the fool who thinks breathing is respiration…
Definitions Respiration is the chemical reaction that break down nutrient molecules in living cells to release energy. Aerobic respiration the chemical reaction in cells that use oxygen to break down nutrient molecules to release energy Anaerobic respiration is the chemical reaction in cells that breaks down nutrient molecules to release energy without using oxygen Respiration involves the action of enzymes in the cell
What are the uses of energy in the body? • • • • • • •
muscle contraction protein synthesis cell division active transport growth the age of nerve impulses maintenance of a constant body temperature

What is respiration? Respiration is the process that the body uses to release energy from digested food (glucose). It is a chemical reaction. carbon glucose + oxygen water ( + energy) + dioxide from the digestive system
from the respiratory system
waste product (exhaled)
waste product (exhaled)
This type of respiration is called aerobic respiration because energy is released in the presence of oxygen. How do the glucose and oxygen needed for aerobic respiration get to the all the body’s cells?
Our important systems...
If we now think back over the journey of oxygen and digested food through the human body, we will realise that they both end up in the same place. food
oxygen
breathing system
these substances eventually arrive at the body cells
digestive system
BLOOD
Every living cell needs to respire Therefore, the raw materials for the energy-making process eventually arrive at the body cells. This energy-making process is known as...
R E S P I R A T I O N Each living cell is supplied with food and oxygen in order to generate energy. capillary blood oxygen muscle cell

What is anaerobic respiration? Aerobic respiration uses oxygen to break down glucose. It releases a lot of energy from each glucose molecule by breaking it down completely into carbon dioxide and water. Glucose + oxygen carbon dioxide + water C6H12O6 + O2 CO2 + H2O A* TASK BALANCE THIS EQUATION
