Bio Test Part 3
for bio test
What is the function of the pancreas?
senses blood sugar levels and produces two hormones, glucagon and insulin
What is glucagon?
raises blood glucose levels. induces glycogenesis in liver and gluconogenesis in adipose
what is glyconogensis?
What is gluconogenesis?
What is insulin?
lowers blood glucose and induces glucose uptake by liver, muscle and adipose cells. induces glycogen and fat synthesis
What kind of cells produce glucagon?
what kind of cells produce insulin?
What are some types of plant hormones?
peptides and RNA's along with auxins, gibberellins and absciscic acid
What are gibberellins?
they enhance plant growth and are often used on seedless grapes
What is abscisic acid?
a stress hormone. It coordinates plant responses to abiotic environmental responses. It also slows or stops plant metabolism when growing conditions are poor
What are auxins?
master plant hormones that induce vascular tissue to differentiate, promotes root formation and stimulates fruit development
What are some effects of auxins?
stimulates seedless fruit production
retards premature fruit drop
pinching shoot buds produces bushy plants
used as herbicides (agent orange)
Where is auxin mainly produced?
apical shoot tips and young leaves
Highly localized patterns of hormone action result from...
localized patterns of transport
localized patterns of synthesis
localized patterns of degradation or inactivation
localized patterns of expression of signal transduction and response regulators
