which groups of organism produce energy via cellular respiration Solution Organi

Question

Explanation / Answer

Organism is the tiny living thing that you only see with microscope. Certain bacteria and yeast is the correct one. Cellular respiration falls into 2 categories : 1) Aerobic respiration (Certain bacteria and yeast) ? Process that requires a continous supply of oxygen for the oxidation of glucose to produce carbon dioxide, water and energy. --------------------------------------… Glucose + Oxygen ==> Carbon dioxide + Water + Energy C6 H12 O6 + 6 O2 ==> 6 CO2 + 6 H2O + 2898 kJ --------------------------------------… ? Glucose is partially broken down in the cytoplasm (no oxygen necessary here) and complete oxidition takes place in the mitochondria. This is because the enzymes for the specific reactions are present in the different parts of the cell. ? Along the way to complete oxidation (when glucose is converted to carbon dioxide and water), energy is released in small 'packets' and used to synthesise adenosine diphosphate (ADP) and inorganic phosphate. ATP can then used as and when needed. --------------------------------------… ADP + phosphate + energy ==> ATP --------------------------------------… 2) Anaerobic respiration (Yeast) ? Carried out anaerobic respiration in the absence of oxygen by producing carbon dioxide, ethanol, and energy. ? Anaerobic respiration in yeast called fermentation and is catalysed by an enzyme called zymase. --------------------------------------… Glucose ==> Ethanol + Carbon dioxide + Energy C6 H12 O6 ==> 2 C2 H5 OH + 2 CO2 + 210kJ --------------------------------------… ? Anaerobic fermentation in yeast is used to make ethanol (alcoholic drinks). ? Production of carbon dioxide by yeast is used to produce the fluffy texture of bread.
