Bio / Biochem 2 Flashcards
Kc
Kc = [PDTs] / [reactants]
If Kc = 0.5, there’s 2x as many reactants as products
If you started under standard conditions, you’re starting at 1M each
Since in the balanced equation Reactants : Products are in a 1:1 ratio, you should end up with 2M total at the end too
Adenylyl cyclase
- lyase
- Mg2+ cofactor
RBC
no nucleus
parenchyma
-functional cell
vs connective tissue - supportive
bone, cartilage, tendons, ligaments, adipose, blood
PPP RLS
-Glucose-6-P dehydrogenase
UDP-gal epimerase
convert hexose epimers
ex- galactose to glucose
Thyroid
TRH -> TSH –| TRH
TSH-> T3/T4, whose production involves iodine uptake + thyroglobulin synthesis
= hypertrophy (bigger) / hyperplasia (more cells)
Goiter = enlarged thyroid
-Iodine deficiency = can’t make thyroid hormones = high TSH = enlarged thyroid / goiter
Cross sectional studies
- same point in time, many groups
- PREVALENCE
- NOT causation/correlation or incidence of new cases/year
Bacteriophage
-capsid, tail sheath, tail fibers
tail fibers identify host proteins - what it can infect
Waxes
long chained esters
Thymocyte
T-cell
- must recognize self-MHC (pos selection) but not self-antigen (neg selection)
- MHC for getting activated
T cell maturation facilitated by THYMOSIN (peptide hormone) - secreted by thymic cells
-naive until exposure to antigen and clonal selection
systemic
-whole system- central and peripheral - circulate in blood
“sufficient”
is a strong word
-only if you control for internal validity / confounding variables
Thyroxine
-system-wide effect
-enters nucleus, activates genes
T4
T3 = triiodothyronine
Less exercise
= use less calories
= increase body fat deposition
