In comparison to eukaryotes, prokaryotes -Are smaller and lack a nucleus-
Answer:
It's true that anabolic steroids used by some bodybuilders and athletes contain testosterone or chemicals that act like testosterone. The difference is that doses used in testosterone replacement only achieve physiologic (natural) levels of hormone in the blood.

When the bond between the second and third phosphate group is broken in ATP, ADP is formed and energy is released. This energy can power the cell's functions.
If the temperature is too low, enzyme molecules don’t have enough kinetic energy to collide and combine with other substrate molecules. So the enzyme activity/ reaction rate will be very low. The rate will rise again once the temperature increases to its optimum temperature.
But if the temperature is too high, enzyme will be denatured, which means the shape of the active site of the enzyme is changed. It can no long combine with other substrate molecules. The rate will drop significantly. Yet, lowering the temperature won’t help because denaturation is permanent and irreversible.
C. Temperature and pH can affect how enzymes work
Enzymes show a maximum activity at an optimum pH and temperature. Changes in the pH or the temperature can cause damage in the structure of the enzymes, if the structure changes the substrate can no longer bind to the enzyme, which is why the activity of the enzymes starts to slow down.
