Unit 3: Energy Systems Flashcards
List the micronutrients and macronutrients:
Micro → vitamin and mineral
macro → Lipid (fat), carbohydrate, water and protein.
state the chemical composition of a glucose molecule
C, H and O. (1:2:1 ratio)
Glucose molecules can combine to form…
polysaccharides and disaccharides
What si the condensation reaction?
the linking of a monosaccharide to another monosaccharide, disaccharide or polysaccharide by the removal of a water molecule.
State the composition of a
molecule of triacylglycerol.
1 glycerol and 3 fatty acids
State the chemical composition of a protein molecule.
C, H, O, and N.
Outline metabolism
All the biochemical reactions that
occur within an organism, including anabolic and
catabolic reactions.
outline anabolism
Energy requiring reactions whereby
small molecules are built up into larger ones.
outline catabolism
Chemical reactions that break down
complex organic compounds into simpler ones, with the net release of energy.
State what glycogen is and
its major storage sites.
Glycogen is stored glucose. It is stored in the liver and the skeletal muscle.
State the major sites of
triglyceride storage.
Adipose tissue and muscle
Outline glycogenolysis.
The break down of glycogen into glucose
Outline lipolysis.
The breakdown of lipids into glucose.
Define cell respiraton
the controlled release of energy in the form of adenosine triphosphate (ATP) from organic compounds in cells.
