What EKG leads would you expect to see ST elevations in if a patient has a septal myocardial infarction?
If a patient has an infarction of the septal region, you would expect to see ST elevations in the septal leads: V1 and V2.
What will happen to the pressure of a gas if the volume of its container decreases? How do you know this?
If the volume of a container holding a gas decreases, the pressure of the gas will increase. We know this because of Boyle's law, which states that the pressure of a gas will increase as volume decreases. This assumes that temperature remains constant.
What is the first committed step of glycolysis and why is this important?
The first committed step of glycolysis is the phosphorylation of fructose-6-phosphate to fructose-1,6-bisphosphate by phosphofructokinase 1. This step is important because the reaction is essentially irreversible and commits the glucose molecule to glycolysis.
