Frequently asked questions
What is Topic 8: Exchange and transport in animals?
Exchange surfaces, blood, circulation, the heart and respiration. 14 lessons in 3 subtopics.
What is the equation for anaerobic respiration?
In muscles, anaerobic respiration is glucose → lactic acid. The Anaerobic Respiration and Fermentation notes cover this in full.
What is haemoglobin?
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.
What is the word equation for aerobic respiration?
The word equation for aerobic respiration is glucose + oxygen → carbon dioxide + water + energy. The Aerobic Respiration notes cover this in full.
What is plasma and what does it carry?
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.
What is metabolism?
Metabolism is the sum of all chemical reactions that occur in a cell or organism. The What is Metabolism? notes cover this in full.
What is lactic acid?
Lactic acid is a toxic waste product formed during anaerobic respiration in muscles. The Anaerobic Respiration and Recovery notes cover this in full.
What are the four components of blood?
Blood is made of plasma, red blood cells, white blood cells and platelets. The Components of Blood notes cover this in full.
What is anaemia?
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.
