respiration is oxygen + glucose > carbon dioxide + water ( + energy) it is not breathing. it is a chemical reaction which takes place in all cells and results in the release of energy. this energy is released from food , mainly glucose that cells take in.

the energy released is used for

~muscle contraction and movement

~growth and repair by producing proteins

~nervous activity

~heat regeneration

~allows all life processes to be carried out ( mrsgren)

hope this is what you were after .

Respiration is the process of oxygen diffusing into our blood and being pumped around our body. Its sole purpose is to release energy from the food we eat. The equation for respiration is glucose + oyygen --> (energy) CO2 + water.

There are two types of respiration, anaerobic and aerobic, aerobic simply means 'with oxygen' and vice versa for anaerobic. Aerobic respiration occurs when oxygen is present, whilst anaerobic occurs when there is a lack of oxygen, or an 'oxygen debt'. An example of this is when you run and get a stitch, this is where your body respires anaerobically to receive energy, which produces lactic acid as a by- product and causes muscle tiredness/stitches.

A bit further into the topic, but thought it was a little interesting fact for you :)

respiration is the process of using glucose to make energy.

this can be aerobic or anaerobic and is used in both plants and animals

aerobic respiration (with oxygen):

glucose + oxygen --> carbondioxide + water + energy

anaerobic respiration (without oxygen) in animals:

glucose --> lactic acid + little energy

anaerobic respiration in plants:

glucose --> ethanol + carbondioxide + little energy

Respiration-animals way to release oxygen into the atmosphere.It can also be the action of breathing for humans.

respiration releases carbon dioxide not oxygen.

Respiration isn't breathing - breathing is the process of the lungs, muscles and ribs moving, and RESPIRATION IS THE PROCESS OF GETTING OXYGEN INTO THE BLOOD

glucose +oxygen ---> energy + carbon dioxide + energy

Hope this helps :)
