Respiration

• what is respiration ?

  The process of converting glucose into energy in the presence of oxygen
• what substance is energy used to make from respiration ?

  ATP
• what does ATP do ?

  store energy needed for many cell processes
• what happens when a cell needs energy ?

  ATP molecules are broken down and energy is released
• what are the 2 types of respiration ?

  aerobic and anaerobic respiration
• is cellular respiration endothermic or an exothermic reaction ?

  exothermic
• does aerobic respiration need oxygen or not ?

  needs oxygen
• does anearobic respiration need oxygen or not ?

  doesnt need oxygen
• what is the word equation for aerobic respiration ?

  Glucose + Oxygen -> Carbon Dioxide + Water (+ Energy)
• what is the balanced chemical equation for aerobic respiration ?

  C6H12O6 + 6O2 -> 6CO2 + 6H2O (+ATP)
• how much ATP is produced during aerobic respiration ?

  32 molecules per molecule of glucose
• what is the definition of aerobic respiration ?

  the chemical reaction in cells that uses oxygen to break down nutrient molecules to release energy
• what is the definition of anearobic respiration ?

  chemical reaction in cells that breaks down nutrient molecules to release energy without using oxygen
• where are the 2 types of anearobic respirations occuring ?

  • occurs in muscles producing lactic acid
  • occurs in plants producing alcohol and carbon dioxide
• what is the word equation for anaerobic respiration in animals ?

  glucose -> lactic acid (+energy)
• what is the word equation for anaerobic respiration in plants ?

  glucose -> ethanol + carbon dioxide (+energy)
• does aerobic or anaerobic respiration release more energy ?
