Lecture 4 Cell Signaling and Hormonal Responses to Exercise

QuestionAnswer
_______-soluble hormones can enter the nucleus of the cells and alter cell DNA Lipid
_______- soluble hormones bind to membrane receptors and trigger action within cell membrane Water
True or False: Plasma glucose is a fuel source at all exercise intensities True
List the 4 ways to maintain plasma glucose... glycogenolysis, gluconeogenesis, lypolysis, blocking glucose entry/ decreasing the rate of glucose utilization by cells

___________ hormones are permissive hormones Thyroid
_____________ and ___________ __________ are slow-acting hormones Cortisol and growth hormone
______________, _________________, and _____________ are fast acting hormones Epinephrine, Norepinephrine, and glucagon
Thyroid hormones are stimulated by... Decreased plasma levels of T3 and T4
_________ hormones increase the number of receptors or affinity of receptors to bind to other hormones Thyroid
During exercise ___________ ___________ unbind from transport protein but are readily removed from plasma by tissue Thyroid hormones
Cortisol is released from the __________ __________ Adrenal Cortex
Exercise, bone breaks, burns, and stress trigger the release of __________ Cortisol
Of the 4 ways to maintian plasma glucose cortisol contributes to _____________, ______________, and ______________________ Gluconeogenesis, lypolysis, decreased rate of glucose utilization by cells

Insulin is secreted by _____ cells in the _________ Beta cells in the pancreas
During exercise insulin secretion ____________(increases/decreases) Decreases
__________ is secreted when plasma glucose is high, amino acids are high, and increased parasympathetic activity Insulin

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
