Telomerase
Give this one a try later!
is an enzyme that created an extension to the unreplicated end of DNA
strand
DNA primase and DNA polymerase III can then synthesise the lacking
piece of DNA
Second law of thermodynamics
Give this one a try later!
- Every energy transfer of transformation increases the entropy ('disorder')
of the universe
,Cytoskeleton
Give this one a try later!
- Essential for cell shape and cell support and cell movement
- Three types of filaments
- Microtubules
- microfilaments
- intermediate filaments
Catabolic reaction / exergonic
Give this one a try later!
break down molecules and release energy
- neg delta G
- Release energy
- Has activation energy barrier
- Reactant energy level: HIGH
- Product energy: LOW
ATP synthesis - hydrolysis
Give this one a try later!
, - Most common forms of stored cellular energy - ATP (adenosine
triphosphate)
- Contains chemical energy in bonds between 3 phosphate groups
- After breaking down nutrients, the energy released is converted to ATP
- When ATP broken down to ADP (1P removed) this energy is released and
can be used
Proteins
Give this one a try later!
Consists of one or more polypeptides (polymer of amino acids)
Phospholipid
Give this one a try later!
- Have two fatty acids
- have a phosphocholine group instead of a third fatty acid
- quite charged and makes the head hydrophilic
- hydrophobic tails
- result in bilayer arrangement found in cell membranes to allow semi-
permeability
Three basic cells in life
