Resumen del Recurso
Living and Growing
Molecules of Life
Cell Structure
Number of mitochondria in cytoplasm dep. on cell activity
Where respiration occurs
Muscle/liver cells: High concentration
Ribosomes
< Mitochondria
Site of protein synthesis
DNA
Double Helix
4 bases: A-T G-C
Each 3 pairs: 1 Gene
Messenger RNA (mRNA) carries code to ribosomes
Many proteins made are Enzymes, controlling cell activity
Complimentary pairs
Watson and Crick
Built double helix based on:
X-rays showed DNA wound in double helix
Data indicated it occurred in in pairs
Discovered DNA in 1953, nobel prize in 1962.
Delay because other scientists had to corroborate
Proteins + Mutations
Long chains of amino acids
Each with unique amino acid number + order
Results in different function
Protein Functions:
Structural eg. Collagen
Build cells, tissues
Hormones eg. Insulin
Control body functions
Carrier proteins eg. Haemoglobin
Carries oxygen
Enzymes:
Speed up bodily reactions
Biological catalysts speed up:
Respiration
Photosynthesis
Protein Synthesis
'Lock and Key' mechanism
Substrate comes together with enzyme
Separate Products made
Optimum: Best temp. and pH
At low temps. molecules move slowly
High temp. Denatures enzymes
pH extremes denature enzymes
Calculated by Temperature Coefficient:
"Q10 = Rate at higher temp' / Rate at lower temp'
