Anaerobic respiration

12.3

What the syllabus asks of you

Describe anaerobic respiration as the chemical reactions in cells that break down nutrient molecules to release energy without using oxygen
State that anaerobic respiration releases much less energy per glucose molecule than aerobic respiration
State the word equation for anaerobic 5 State the balanced chemical equation for respiration in yeast as: anaerobic respiration in yeast as: glucose → alcohol + carbon dioxide C6H12O6 → 2C2H5OH + 2CO2
State the word equation for anaerobic respiration in muscles during vigorous exercise as: glucose → lactic acid 6 State that lactic acid builds up in muscles and blood during vigorous exercise causing an oxygen debt continued Core Supplement 7 Outline how the oxygen debt is removed after exercise, limited to: (a) continuation of fast heart rate to transport lactic acid in the blood from the muscles to the liver (b) continuation of deeper and faster breathing to supply oxygen for aerobic respiration of lactic acid (c) aerobic respiration of lactic acid in the liver
