The enzyme phosphorylase kinase catalyzes a modification of glycogen phosphorylase that controls its activity. How does phosphorylase kinase modify glycogen phosphorylase?

a. adenylation, which transfers an adenosine from ATP to the phosphorylase enzyme direct AMP

b. binding to glycogen phosphorylase after hydrolysis phosphorylation, which transfers a phosphate from ATP to the phosphorylase enzyme

c. a conformational change driven by the energy released when ATP is hydrolyzed

The phlogiston theory in the 17th century attempted to explain burning. the theory stated that combustable objects contained a material called phlogiston, a substance without mass, color, odor, etc. after objects burned, the objects were dephlogistonated and were then in their true form. the phlogiston theory was accepted until the 18th century, when lavoisier proved that combustion requires a gas that has mass. phlogiston is considered a) to be scientific knowledge b) not to be scientific knowledge c) to be proven by scientific method d) to be accepted in the modern scientific community
