Essay Topic Ideas Flashcards
How proteins can relate to an enzyme topic?
Tertiary structure
creates unique, specific active site
3D shape
Importance:
Induced fit model
Lowering activation energy
Alevel Enzyme Examples such as endopeptidases, ATPase
How proteins can relate to a transcription factors topic?
Tertiary structure
creates unique, specific DNA binding site on the TF
3D shape
Importance:
Inhibiting/initiating transcription of tumour suppressor genes
Can lead to uncontrolled cell division and cancer
How proteins can relate to a membrane proteins topic?
Tertiary structure
creates unique, specific binding site so only certain molecules can bind
3D shape
Role of proteins in Facilitated diffusion
Importance:
Examples of FD eg absorption of AAs/glucose in ileum
Action potentials
Chemiosmosis
Translocation
How can proteins relate to an immunity topic?
Quaternary structure
Specific 3D binding site
Complementary to only one antigen type
Importance:
Agglutination
Vaccinations
Monoclonal antibodies
How proteins link to skeletal muscles in an essay?
Myosin and actin protein filaments
Myosin head able to bind to the binding site on actin
Importance:
Sliding filament theory
Skeletal muscle contraction
Diaphragm contract example - link to breathing
How proteins link to tissue fluid in an essay?
How tissue fluid forms
Large soluble plasma proteins remain in the capillary
Importance:
these proteins lower wp of blood so water moves back in via osmosis
so waste can diffuse into blood then diffuse out of alveoli (gas exchange)
How proteins link to haemoglobin in an essay?
quaternary structure
heme groups = oxygen binding site
cooperative binding
Importance:
transport of oxygen as it’s the terminal electron acceptor in respiring cells ETC
enables maximum ATP production
How proteins link to cardiac muscle in an essay?
Heart has myogenic muscle
Thicker around ventricles than atria
Importance:
Pumps oxygenated blood to respiring cells at high pressure
Oxygen is terminal electron acceptor in ETC of respiration
Enables max ATP production for metabolism and use in active transport etc
How chemiosmosis can link to respiration?
Process of it in oxidative phosphorylation
Importance:
producing ATP for metabolic purposes
How chemiosmosis can link to photosynthesis?
Process of chemiosmosis in LDR
Production of ATP and NADPH needed for Calvin cycle for making organic substances
How chemiosmosis links to ATP
Process of chemiosmosis in oxidative phosphorylation and mainly on how ATP is made
Importance:
ATP used for metabolic processes
How chemiosmosis can relate to movement of ions?
Chemiosmotic process, focusing on H+ movement
importance:
producing ATP for metabolic processes
how can chemiosmosis link to conc gradients?
focus on electrochemical gradient in the process
importance:
facilitated diffusion of H+ enabled
through ATP synthase
producing ATP for metabolic processes
How can chemiosmosis link to facilitated diffusion?
Focus on FD of H+ through ATP synthase
importance:
produces ATP for metabolic processes
how can chemiosmosis link to membranes?
describe chemosmosis but focus on EC gradient created due to H+ being unable to diffuse through the cristae membrane, so must pass through proteins
importance:
enables production of ATP for metab processes
H+ must pass back through ATP synthase
