An enzyme may catalyze a reaction by stressing or destabilizing the bonds of the substrates. this critical point in the enzymatic reaction is known as the

Catalysis An enzyme may catalyse a reaction by stressing or destabilizing the bonds of the substrates. This point in the enzymatic reaction is known as the Transition State.  An enzyme can couple a nonspontaneous reaction to a spontaneous reaction so that anabolic processes will occur.

meiosis is the first to occur after the nuclei of opposite of opposite mating types fuse

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
