Winter’s Flashcards
What do lamella do
Increase surface area so diffusion rate is optimum rate
ATP hydrolysed
To make ADP + P through hydrolase releases cellular energy
ADP condensation
Use ATP synthesise puts energy back together creating ATP
What does ATP contain
Adenine ribose and three phosphates
Phospholipid bi layer
Allow lipid soluble membranes though not water soluble due to hydrophobic tails
Channel proteins
Let small water soluble molecules though
Carrier proteins
Can only pick up one type of molecule at once
Cholesterol
Add strength to the molecules reducing lateral movement
Glycoproteins
Help cell attach to another so it forms tissues
Polysaccharides
Polymers combining together many monomersaccride molecules joined by glycosidic bonds
Glycogen structure
Alpha glucose monosaccharide 1-4 and 1-6 Glycocidic bond Branched shape storage of glucose
Significance of glycogen
Easily hydrolysed to realise glucose
Magnification needs
Pencil, no shading, clear continues lines, accuracy
Abdominal pumping
Larger insects pump their abdomens in and out using muscles helps fresh air to enter the trachea
When spiracles open
Air moves in through spiracles
Oxygen diffuses down the concentration gradient towards cell Through the trachea through direction diffusion
