what happens during diastole
atria contract
av valves open
closing of semilunar valves
what happens during the systole phase
ventricles contract
av valves close
semilunar valves open
function of yeast under anaerobic respiration
oxidize NADH to NAD+
cholecyotokinin is what
hormone
cholecystokinin stimulates what
- gall bladder to release bile
- pancreas to release lipases
- decreases the motility of the stomach to provide more time for duodenum to digest fat
desmosomes
cell to cell adhesion
hemidesmosomes
cell to ECM connection
product of light dependent reaction
O2, ATP, NADPH
product of light independent reaction
Glucose, ADP, NADP+
hypothalamus controls what

5 to 3
Cadet stands for
carbon dioxide acid 2,3 diphosphoglycerate Exercise Temperature
An increase in Cadet will shift in what direction
right
decrease in cadet will shift in what direction
left
what initiates membrane potentials
release of acetylcholine at the neuromuscular junction which triggers an action potential
where does translocations happen
elongation of translation
3 stop codons
UGA UAA UAG
name the steps for alternation of generation
sporophyte - meiosis - spores - mitosis - gametophyte - gametes - zygote - mitosis - sporophyte
another name for hypodermis
subcutaneous tissue
what is oxidative phosphorylation (made up of what two things)
made up of electron transport chain and chemiosmosis (diffusion of ions across a semi permeable membrane)
reflex arc
muscle movement coordinated by the spinal cord instead of the brain
concentric contraction
muscle shortened
eccentric contraction
muscle is lengthened
isometric contraction
muscle tenses but length reamins the same
Anterior pituitary produces what
FLAT HP FSH LH ACTH TSH HGH prolactin
posterior pituitary produces what
oxytocin and ADH
pineal gland produces what
melatonin
steps for embryonic development
zygote morula (solid ball) blastula (hollow sphere of cells) bastocyst gastrula (3 layers formed) replaces the hollow sphere
what two hormones have negative feedback on the hypothalamaus and pituitary gland?
estrogen and progestoerone
bacteria naming hints
staph = grape like clustes diplo = pairs strep = chain coccus = spherical bacillus = rod like
antibodies such as IgG does what
destroy antigens by binding to them with one of their variable binding sites.
what is the variable sites of IgG (relates to all the other ones..)called?
hypervariable region contains residues that binds to corresponding antigens
bile is made where? stored? and secreted through what tube?
liver
gallbladder
common bile duct
def of nondisjunction
failure of one or more chromosome pairs to separate properly during anaphase. ends up producing daughter cells with the incorrect number of chromosomes.
function of aldoesterone
increase Na+ reabsorption and K+ excretion, H20 reabsorption, increase blood volume and blood pressure (targets the kidneY)
bacterial cell walls are made out of what
peptidoglycan
ligaments connect what
bone to bone
tendons connect what
muscle to bone
what cells secrete glucagon which raises blood sugar?
alpha cells
what cells secrete insulin which lowers the blood sugar
beta cells
hypothyroidism
reduced matabolic rate
- lethargy
- weight gain
low heart and respiratory rate
hyperthyroidism
increased metabolic rate
- hyperactivity
- weight loss
- anxiousness
