The diagram below represents the cell cycle. When cells leave the cell cycle, they exit during g1 phase and then enter g0 phase a resting period. Most normal cells can leave g0 phase and reenter the cell cycle at G1 phase before entering S phase. Cancer cells are different because they cannot enter G0 phase and are likely to do which of the following? A. Die after completing mitosis
B. Repeat the cell cycle continuously
C. Mutate during G1 phase
D. Fail to complete S phase

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.

sound moves fastest in solids because the molecules are tightly packed and it allows sound to vibrate
