module 5 proteins Flashcards
what does panacea mean
“cure all”
What is a protein
- component of every living cell
- made up of AA
- Every AA contains N
what is the primary structure of a protein
linear order of amino acids
what is the secondary structure of a protein
the shapes within the protein
what is the tertiary structure of a protein
final 3-D shape of protein
what is the structure/function relationships with proteins
the AA sequence (primary structure) of a protein determine its final 3D shape
T or F Altering amino acid sequence can change a proteins function dramatically
True
What is the structure of hemoglobin protein
- RBC
- full of hemoglobin
- 4 identical protein units
what does protein do when regulating body processes
produces some hormones like insulin and glucagon
contains enzymes like lipase, amylase and trypsin
Neurotransmitters; serotonin
what do proteins do with growth and repair of tissues
muscle protein: actin and myosin
collagen plays a big structural role
what is normal turnover
the breaking down and replacing of tissues and organs
what does protein immune defence do
create antibodies
what is protein transportation
hemoglobin: transports oxygen
transferrin: iron taxi (blood transport protein)
what does protein do for energy
any protein consumed may be digested and resulting AA used for energy (4Kcal)
T or F protein is the least “expensive” form of Kcal for the body
False its the most
