RESPIRATION

RESIRATION
 * Some organisms breathe just like human.
 * To make it work, we need oxygen and at smae time, CO2 goes away.
 * It makes energy and food.
 * It occurs in living cells.
 * It includes the chemical break down to make energy.
 * Plants and animals have living cells.

so it is better if it is thinner. ||= Blood containing O2 is carried around body and it gives out enrgy to different cells. ||
 * = FEATURE ||= Large surface area ||= Moist ||= Link with capillaries ||= Very thin ||= Way to provide oxygen ||
 * = EXPLANATION ||= Helps ability of moving. ||= Gases must leave or enter via solution ||= Blood carries O2 out and brings CO2. ||= Movement is via diffusion



HUMAN RESIRATORY SYSTEM

PLANT RESPIRATORY SYSTEM

AEROBIC RESPIRATION
 * It is a simple process where food gets broken down and where energy is given out.
 * Most organisms do this.
 * Most broken down food turns into glucose.
 * 'AEROBIC' means requiring air.
 * Dozens of seperate reactions must be done.

ANAEROBIC RESPIRATION


 * It is most efficiency way to get energy wihout food, using oxygen.
 * It doesn't break down fully into smaller substances.
 * It works when a cell can't get energy from energy so they convert glucose by lactic acid.
 * When making glucose with lactic acid it never makes CO2 or H2O.
 * It works the most at muscle.
 * The body uses leftover lactic acid usefully.

RESPIRATION IN PLANTS
 * Knowing that plants also breathe like us is important.
 * They are unique that they release oxygen from cells in leaves to make own food.
 * They also can reuse oxygen in aerobic respiration.
 * However some people think that plants don't need oxygen.
