they need oxygen.
C6H12O6 → 2C3H6O3 + 2 ATP Glucose → Lactic Acid + (Energy) Anaerobic respiration refers to the oxidation of molecules in the absence of oxygen to produce energy. Since energy cannot be expressed chemically it is not always recognised as a product in equations but it is, however, still produced as a result of this reaction.
There are many ways in which humans release the energy they eat from food. They can work out for example.
Energy is stored as chemical energy in human body. It is consumed when required.
Metabolism is the use of energy by cells. All animals get energy from nutrients through metabolism. Humans an other animals eat food to get energy.
Food (for humans at least) is composed of many Carbon-Carbon bonds, linked together in many different fashions. Basically our body breaks down these bonds, the breaking of which releases energy, which is stored in ATP for us to use.
Food energy is energy that animals (including humans) derive from their food, through the process of cellular respiration, the process of joining oxygen with the molecules of food (aerobic respiration) or of reorganizing the atoms within the molecules for anaerobic respiration.
Aerobic respiration in humans is: Glucose + Oxygen → Energy + Carbon Dioxide + Water Anaerobic respiration in humans is: Glucose → Lactic Acid + Energy
Oxygen is needed for the chemical reaction which provides humans and animals with the energy that we need to make our biochemistry work.
So Easy...Its ATP
helps with release of energy

Ummm... Best, for what? Several types of energy are essential for our survival.
Energy is stored as chemical energy in human body. It is consumed when required.
humans take food in order to have energy that will enable them to carry out processes of life e.g cellular respiration requires energy that we get from food.
Metabolism is the use of energy by cells. All animals get energy from nutrients through metabolism. Humans an other animals eat food to get energy.
Decomposers get energy in much the same way as heterotrophs (e.g. humans) obtain energy. They take organic matter called detritus (e.g. dead leaves, wood etc.), and take the chemical potential energy out of it. Wood, for example, has much chemical potential energy (as you can tell from a wood fire). Decomposers break apart the cellulose in the wood into sugar monomers, and then do cellular respiration to "burn" it. Humans only differ in the source of the sugar molecules; rather than obtaining the sugar molecules from, say, potatoes decomposers obtain them from detritus.
