Glucose + Oxygen = Co2 + H20 + Energy
P4 Explain the physiology of two named body
systems in relation to energy metabolism
Define energy (definition)
Outline Newton’s two Energy Laws
Describe energy forms (kinetic, chemical)
Describe energy metabolism (catabolism and
anabolism)
Give examples of how energy is used in the
body
Describe respiration (aerobic and anaerobic)
Describe ATP (where made in cells, equation,
what it looks like)
M1 Discuss the role of energy in the body
Where energy comes from (dietary sources)
What it is measured in
The energy equation
Digestive (merit additions):
Process of Glycolysis, glycogenolysis, enzymes,
sites of secretion, absorption and epithelium,
lacteals, villi, microvilli, role of the liver,
pancreas, kidneys, ingestion, digestion,
absorption, egestion, storage of fat and
glucose and protein
Cardiovascular (merits additions):
Cardiac cycle, stroke volume, pulmonary,
systemic circulation, haemoglobin and O2
uptake, structure of blood, blood glucose
levels,
Outline the digestive system: explain how it
transports and metabolises energy
Outline the cardiovascular system: explain
how it transports and metabolises energy
Explain the physiology of two body systems
in relation to energy metabolism
(cardiovascular and digestive)
For example, a pass might involve telling the story of how the heart pumps blood to the lungs via the
pulmonary artery to take up oxygen from the inspired air and at the same time releasing the waste
product of carbon dioxide. For a merit, an explanation would include details of ventilation, the
cardiac cycle and the role of haemaglobin.
D1 Analyse how two systems interrelate with
each other to perform a named function/s
Respiratory
Supplies the body with Oxygen (used in
aerobic respiration)
Gets rid of CO2 (by product of aerobic
respiration)
Uses energy for active transport of gases
Cardiovascular System
Blood transports gases used in respiration
Heart pumps blood around your body
containing gases
Uses energy for active transport
Nervous System
CNS controls and regulates heart rate/cardiac
cycle – adrenaline
Uses energy for repair
Endocrine System
Hormones travel around your body in the
blood
Insulin (hormone) used to regulate glucose
absorption (released from islets of langerhans
-beta cells- in pancreas)
Digestive System
Food contains energy we need
Ingested into body
Absorption from small intestine into blood
stream
Uses energy (digestive enzymes)
