Geologic time scale refers to a system of chronological dating which relates geological strata to time. Geologic time scale is used by scientists to describe the timing of the events that had occurred in the past, thus the scale divides the earth history into units of varying magnitude. There are four basic block of time, these are eons, eras, periods and epochs.
In determine geological time, rock records provide evidence of past geological events and life forms.
Answer:
Binding of glucose to hexokinase causes a conformational change in the enzyme. This is an example of the<u> induce-fit </u>model of enzyme catalysis.
Explanation:
The induce- fit model is generally the most accepted theory for enzyme catalysis. This theory states that the active site of an enzyme is not always a perfect fit for a substrate. The substrate induces changes in the active site so that it can fit into the active site. This theory is contrary to the theory of lock and key model, which stated that substrates exist as a perfect match for particular active sites of an enzyme.
