Answer:
The two types of lipoproteins are low density lipoprotein and high density lipoproteins
Explanation: As applying to low density lipoproteins (LDL), these are sometimes called the bad cholesterol because a high LDL level leads to a build up of cholesterol in the arteries. This condition narrows the arteries and increases the risk of heart attack, Strom and peripheral artery diseases.
High Density Lipoproteins (HDL), also known as the good cholesterol acts as a scavenger carrying LDL away from the arteries and back to the liver where the LDL is break down and passed from the body.
Answer:
D) It is a coordinator of the processes of glycolysis and the Krebs cycle.
Explanation:
Phosphofrutokinase is a very important enzyme in glycolysis, as it acts as a regulating factor of the glycolytic process that catalyzes a phosphorylation: the conversion of fructose 6-phosphate and ATP into fructose 1,6-bisphosphate and ADP. This is an allosteric enzyme, which is activated by citrate and ADP, but is inhibited by the presence of ATP that endorses the enzyme that its work is not needed at the moment. Although very important in glycolysis, this enzyme is not part of the krebs cycle.
