enzyme & system basics
In the "lock-and-key" model, what fits into the enzyme’s active site?
what is substrates
cannot produce insulin
what is type 1 diabetes
name 2 of the 3 hormones produced by the thyroid gland
what is triiodothyronine, thyroxine or calcitonin
It is an enlargement of the thyroid gland
what is a goiter
This is the general term for growth or movement in a plant stimulated by the environment
what is tropism
Name the three factors that can affect the rate of enzyme activity
what are temperature, pH, and substrate concentration
These specific cells in the islets of Langerhans produce insulin
what is beta cells
breaks down complex structures vs combines substances into complex structures
what is catabolic vs anabolic reactions
These two hormones, produced in the adrenal medulla, promote the conversion of glycogen to glucose for a quick energy boost
what is epinephrine and norepinephrine
the specific hormone responsible for phototropism and gravotropism
what is auxin
compare the nervous and endocrine systems in terms of response time
The nervous system allows the body to adjust quickly, while the endocrine system maintains control over a longer period of time
a persons feels thirsty, has low energy and kidneys can't filter glucose
what is the symptoms of diabetes
Hormone cascade that occurs when your metabolic rate decreases
Hypothalamus releases TRH → Pituitary releases TSH → Thyroid releases Thyroxine
part of the adrenal gland produces cortisol to help the body deal with long-term stress
what is the adrenal cortex
plant shoots grow toward light
what is phototropism
This "master gland" has two lobes and is regulated by the hypothalamus
what is the pituitary gland
When blood sugar is low, alpha cells release this hormone to convert glycogen back into glucose
what is glucagon
This condition involves the broadening of facial features due to high secretions of growth hormone after puberty.
what is acromegaly
This hormone, produced by the thyroid, lowers blood calcium by slowing bone cell activity
what is calcitonin
roots growing toward the ground and shoots toward the sky
what is gravotropism
These hormones are made from cholesterol, diffuse directly into target cells, and activate genes in the nucleus.
what is steroid hormones
Protein hormones use this "secondary messenger" molecule within the cell to activate enzymes.
what is Cyclic AMP
Individuals that secrete high levels of thyroxin oxidize (metabolize) sugars and other nutrients at a faster rate
what is hyperthyroidism
Releasing calcium from bones, absorbing it from the intestine, or stopping kidneys from excreting it in urine
what is the function of the Parathyroid hormone
