Respiration

• ATP stands for adenosine triphosphate, it is the energy currency for life ad every living cell uses ATP to grow, repair and survive
• in ATP, chemical energy is stored in the bonds of molecules.

  -To make bonds=add energy back for storage

  -To break bonds= release energy thats stored in it
• cellular respiration: the process by which organic compounds are broken down to produce ATP energy
• the organic compounds in cellular respiration: lipids, proteins and carbs, but carbs are the cells favourite and will only breakdown the others if theres not enough carbs
• in cellular respiration, the cell will break down glucose in order to convert ADP back into ATP
• ways the cell can break down glucose to convert ADP into ATP:

  • aerobic respiration-lots of oxygen and occurs in the cytosol and/or mitochondria
  • anaerobic respiration-not enough oxygen and occurs only in the cytosol
• The relationship between photosynthesis and respiration:

  • photosynthesis- CO2 + water + light=glucose + oxygen
  • respiration- glucose + oxygen + (release of ATP)=CO2 + water
• feature

  photosynthesis
• definition

  the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
• equation

  CO2+H2O+sunlight=glucose+O2
• where

  thylakoids in chloroplasts
• what

  when plants convert light energy into chemical energy, producing glucose and oxygen as byproducts. Chlorophyll absorbs light, which powers the conversion of carbon dioxide and water into glucose, releasing oxygen into the atmosphere.
• organisms in which it happens

  plants, algae and some bacteria
• feature

  cellular respiration
• definition

  process where glusoce is broken down to resynthesise ATP
• equation

  glucose+O2=CO2+H2O+ATP
• where

  mitochondria
• what

  the process where cells convert glucose into ATP, releasing carbon dioxide and water as byproducts, to provide energy for cellular functions.
• organisms in which it happens

  all organisms
