QuestionAnswer
Are neurotransmitters hydrophilic or hydrophobic? hydrophilic
Are steroid hormones hydrophilic or hydrophobic? hydrophobic
Are peptide hormones hydrophilic or hydrophobic? hydrophilic
Is insulin a hydrophilic or hydrophobic? hydrophilic
Which type of hormone steroid or peptide can pass through the cell membrane. Steroid
Which type of signalling has a receptor on the cell membrane- hydrophilic or hydrophobic hydrophilic
Define signal transduction When an extracellular signal is converted into an intracellular response
Describe what happens after when a peptide hormone binds to its receptor on the cell membrane. A conformational change occurs in the receptor which transduces the signal into an intracellular response
State the two types of intracellular response in hydrophilic signalling 1. phosphorylation kinase cascade 2. G protein activation
State the impact of intracellular signalling enzyme activation OR opening/closing ion channels.
Can hydrophilic signals cross the membrane no
Are hydrophobic signals polar or non polar non polar
In hydrophobic signalling where are the receptors for the steroid hormones cytoplasm or nucleus
When the steroid hormone binds to its receptor what happens next a horomone receptor complex is formed which travels to the nucleus if not already there
State what the Horomone receptor complex does inside the nucleus It binds to HRE within the DNA to influence the rate of transcription
Which type of diabetes is caused by failure to produce insulin from the pancreas type 1
Which type of diabetes is linked to obesity type 2
Describe the cause of type 2 diabetes insulin receptor insensitivity at the liver
insulin receptor acts as a kinase phosphorylating the next enzyme/protein in pathway
Explain why insulin is recommended to treat type 2 diabetes improves glut 4 transporters recruitment to membrane
Describe what happens after phosphoryation kinase cascade glut 4 recruited to membrane in vesicles

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.
