Answer:
The true statements are:
An action potential never occurs in dendrites.
Norepinephrine is a monoamine.
Explanation:
In the following question only two statements are true that are; an action potential never occurs in dendrites as it occurs in nerves to send signals from cell body and axon and transmit it.
The second correct statement is Norepinephrine is a monoamine as these are particular neurotransmitters dopamine, serotonin, also known as catecholamines sometimes.
Thus, the correct answer is :
An action potential never occurs in dendrites.
Norepinephrine is a monoamine.
A baker has created a new strain of yeast which contains no cytochrome c gene and no cytochrome c protein. this will affect what the yeast strain can do to obtain energy. what will this yeast strain do more of compared to a normal strain
Will this new strain of yeast obtain more or less free energy from glucose in its growing medium?
Answer: Less because cytochrome c is key to the electron transport chain.
Explanation:
The Cytochrome c is an essential component of the electron transport chain. Without this there will be no oxidation and reduction of iron atom will take place which could convert the ferrous ions to ferric ions. Thus the entire process of electron transport chain and energy production in the form of ATP will be compromised. So, there will be no production of energy in the anaerobic fermentation by yeast.
