7.2 Energy for action Flashcards
is the basal metabolic rate?
A measure of the minimum energy requirement of the body at rest to fuel basic metabolic processes
what two things can create ATP
ADP and the addition of inorganic phosphate
what are the four stages of respiration?
Glycolysis, the link reaction, the Krebs cycle and the electron transport chain
Why does glucose need to be broken down?
It needs to become more unstable
What are the four intermediates between glucose and pyruvate in glycolysis?
glucose 6 phosphate
fructose 1 phosphate
hexose 1,6 bisphosphate and two triose phosphates
how many ATP’s does glycolysis produce?
two
if oxygen is available, where does the pyruvate pass into?
The mitochondria
what happens during the link reaction?
The two carbon molecule combines with co enzyme A to form acetyl coA
what happens to pyruvate during the link reaction?
It is decarboxylated and then dehydrogenated
what is the starting and ending compounds in the Krebs cycle, not including acetyl coA
citrate and oxaloacetate
how many Kreb cycles are there for one molecule of glucose?
two
during the electron transport chain what moves through the innner membrane and what do they use?
Electrons use membrane bound proteins known as electron carriers
how does the movement of electrons affect the permeability of the inner membrane?
It increases the permeability as the electrons give energy to the inner membrane
due to the movement of electrons in the inner membrane space what is created
An electrochemical gradient
in the electron transport chain oxygen can be considered what?
The final electron acceptor
