Term
spastic paralysis
Definition
acetyl cholinesterase inhibitors prevent Achase from breaking done Ach. so Ach remains attached to Ach receptor sites , Na + continues to flow into muscle, remains contracted
Term
acetylcholinesterase inhibitors
Definition
cause spastic paralysis
nerve gas, tabun, sarin
organophosphate insecticides, malathion,parathion, sevin
Term
flaccid paralysis
Definition
neuromuscular blocking agents
curare
block Ach receptor sites on skeletal
muscle fibers, preventing muscle from contracting
Term
aspirin advil tylenol
Definition
block the release of prostaglandins by injured cells. Actually prevent phophlipids from being turned into prostaglandins?
Term
lidocaine and xylocaine other local anesthetics
Definition
block the conduction of AP in nerve fibers (which nerve fibers? to the brain)
Term
somatic motor neurons
Definition
voluntary conscious control,
originate in gray matter
originate in ventral gray horns or spinal cord at all levels
release Ach to excite skeletal muscle fibers to contract
single innervation
nicotinic Ach receptor sites.
Term
autonomic motor neurons
Definition
autonomous / unconscious
preganglionatec / presynaptic motor neurons rare myelinated and release Ach to excite post ganglionic motor neurons (cholinergic)
postganglionic / post synaptic motor neuron is unmyelinated and release near transmitter onto visceral effector cells
Term
phosphorolation
Definition
ADP +P+energy= ATP
Term
b vitamins associated with
Definition
cellular respiration
Term
ATP
Definition
is a neucleotide, provides energy to all cells, releases energy when chemical bonds are split,
contains phosphate grps
produced by cells in body by the break down of food?
Term
cellular respiration
Definition
glycolysis,
transition reaction,
krebs cycle,
electron transport system
Term
electron transport system
Definition
located in mitochondria,
produces most ATP
uses Oxygen
Term
glycolysis
Definition
glucose is converted into 2 pyruvate sugar molecules / pyruvic acid.
occurs in cytoplasm
for each glucose molecule broken down there is a net gain of 2ATP
Term
kreb's cycle
Definition
acetyl-coA molecules are converted into CO2 during this cycle
where most CO2 is formed
Term
fermentation
Definition
occurs when insufficient O2 is available
Term
transition reaction
Definition
pyretic acid is broken down to acetyl-coA
Term
O2
Definition
is neck for life because O2 accepts the H atoms transferred from hydrocarbon molecules as they are broken down for energy
Term
no carbs available
Definition
body breaks down stored fats forming keto acids
Term
ketoacids
Definition
are formed from the deamination of AA
and incomplete break down of fatty acids
Term
Kreb's cycle
Definition
produces ATP
CO2
reduced coenzymes
Term
Oxidation of one molecule is coupled with
Reduction of another molecule
Definition
loss of H and electrons
gain of H and electrons
Term
when fatty acids & proteins are used for energy
Definition
they are converted to acetyl CoA
Term
urea
Definition
nitrogen containing waste product from the break down of protein
reanimation of Amino Acids
Term
diabetes
Definition
hyperglycemia
catabolism of proteins and fats
production of ketoacids
Term
diabetes
Definition
hyperglycemia
catabolism of proteins and fats
production of ketoacids
Term
diabetes
Definition
hyperglycemia
catabolism of proteins and fats
production of ketoacids
Term
diabetes
Definition
hyperglycemia
catabolism of proteins and fats
production of ketoacids
Term
gluconeogenesis
Definition
the synthesis of sugars from non carbohydrates
Term
electron transport system
Definition
oxidative phosphorylation
Term
elevAted ketoacids levels in bloodstream
Definition
indicate high usage of fats and proteins for energy
Term
glycogen
Definition
is a carb
Term
glucagon
Definition
stimulates glycogenolysis
Term
our atmosphere contains mostly which gas?
Definition
mostly nitrogen
Term
pyruvic acid
Definition
requires O to continue to
or in fermentation reaction converts to lactic acid
Term
total net gain
Definition
38
Term
enzymes chemically are
Definition
proteins
Term
H is carried to Electron Transport System by?
Definition
NAD
Term
catabolic reactions
Definition
hydrolysis and oxidation ?
