In the experiment of anaerobic respiration with yeast i) Why was liquid paraffin poured on glucose? ii) What did you understood about anaerobic respiration? |
|
Answer» i) The supply of oxygen from the air can be stopped by pouring liquid paraffin on glucose. ii) Anaerobic respiration takes place in the absence of oxygen. In this glucose molecule is incompletely oxidised. The end products of anaerobic respiration are ethyl alcohol or lactic acid and CO2 . During anaerobic respiration small amount of energy is liberated (2ATP). Anaerobic respiration occurs in many anaerobic bacteria and human muscles cells. The anaerobicrespiration can be represented as: C6 H12 O6 → 2C2 H5 OH + 2CO2 + 56 K.Cal. |
