List the top 4 most frequently occurring chemical elements in living things.
CHON (Carbon, Hydrogen, oxygen, nitrogen)
List the next 5 important elements needed by living organisms.
SPICKS (Sulfur, Phosphorus, Iron, Calcium, Sodium)
has a role in nerve impulses in animals, maintaining metabolism with bacteria, osmotic balance in most plants.
What property allows a water bug to float on the surface of the water, and allows plants to transport water through their tissues.
Using water as a coolant-Body heat being absorbed by the water molecules evaporating to reduce body temperature.
Or how ponds, lakes or oceans have less variation in temperature.
In Energy Storage
*Energy released faster.
*Soluble in water.
*Easy to move and store.
In Energy Storage
*More energy per gram
*Insoluble in water (No osmosis problems)
*More Oxygen per molecule
*Only good for low energies
*Polypeptide chain more stretched out.
*sheet has twists that increase strength.
(2 Structure) Beta Pleated Sheet
*Long and narrow
*Strength and support in tissues
*Most common in animals
*Keratin in hair and nails
*Pigment and Transport proteins
*Antibodies like haemoglobin and Immunoglobulin
bring about the uptake of glucose across the cell membrane and the storage of glucose as the insoluble polymer glycogen.
reduce the energy of activation and allows a biochemical reaction to reach equilibrium more quickly.
These reactions use enzymes to lower the activation energy, releasing more energy than the activation energy.
When an inhibitor binds to the active site and blocks the substrate. If there are too many substrates, more inhibitors will be made.
Reduces rate of reaction, but does not bind to active site, changes shape of active site.
Parts of a molecule that contain _____ amino acids are hydrophilic and can exist in contact with water.
The lining of the channel itself has _____ amino acids to allow the diffusion of charged molecules and ions.
