In muscles, anaerobic respiration is glucose → lactic acid. The Anaerobic Respiration and Fermentation notes cover this in full.
Haemoglobin is an iron-containing protein in red blood cells that binds to oxygen in the lungs and releases it in body tissues. The Components of Blood notes cover this in full.
The word equation for aerobic respiration is glucose + oxygen → carbon dioxide + water + energy. The Aerobic Respiration notes cover this in full.
Plasma is the pale yellow liquid component of blood that makes up about 55% of blood volume. The Components of Blood notes cover this in full.
Metabolism is the sum of all chemical reactions that occur in a cell or organism. The What is Metabolism? notes cover this in full.
Lactic acid is a toxic waste product formed during anaerobic respiration in muscles. The Anaerobic Respiration and Recovery notes cover this in full.
Blood is made of plasma, red blood cells, white blood cells and platelets. The Components of Blood notes cover this in full.
Anaemia is a blood disorder where there are not enough healthy red blood cells or not enough haemoglobin. The Components of Blood notes cover this in full.
