Food: Water and metabolic reactions Flashcards
1
Q
Functions of water
A
- Universal solvent
- Forms major component of cytoplasm and body fluid
- High heat capacity
- Water is involved in many reactions
- Water easily moves in and out of cell membranes
2
Q
- High heat capacity
A
Water is slow to heat up and cool down
3
Q
- Water is involved in many reactions
A
Photosynthesis
Respiration
Condensation reaction
-> 2 monosaccharide join to make a disaccharide, water is released
4
Q
- Water easily moves in and out through cell membranes
A
Control the shape of cells
5
Q
2 types of metabolic reactions
A
Catabolic reactions
Anabolic reactions
6
Q
Catabolic reactions
A
Complex molecules are broken down into simpler molecules
-Energy is released
7
Q
Examples of catabolic reactions
A
Digestion (disaccharide -> monosaccharide)
Respiration (release of energy from food)
8
Q
Anabolic reactions
A
Simple molecules are combined to make more complex molecules
Energy is taken in
9
Q
Examples of anabolic reaction
A
Protein synthesis
Photosynthesis
(6CO2 + 6H2O -(Sun + Chlorophyll)-> 6O2 + C6H12O6)
