An enzyme is a catalyst which means it changes the speed at which a chemical reaction occurs. It never alters the reaction in any way or changes nay chemical properties, only the speed at which it occurs and is completely absorbed in the meantime. The substrates that are reacting just have their reaction faster.
In biology, cellular communication is a term used to determine distinct kinds of methods of communication among the living cellulites. Of these intercellular communication signifies the communication between the cells. In this kind of communication, membrane vesicle trafficking plays an essential role in both humans and animals.
On the other hand, intracellular communication signifies towards the communication of the organelles in order to sustain cellular homeostasis.
Answer:
Aspects of evolution are constantly being challenged and explored in light of new evidence
Explanation:
The whole idea of evolution has to do with the fact that organisms developed into their present form from simpler life forms. According to Oxford dictionary, evolution is; ''the process by which different kinds of living organism are believed to have developed from earlier forms during the history of the earth.''
Evolution depends on evidence from fossil records. Evidences that support the theory of evolution continue to be amassed as science advances. Hence, aspects of evolution are constantly being challenged and explored in light of new evidence.
For this reason, the evolutionary history and development of whales is being hotly debated and there has recently been a major shift in our understanding of the processes used to detail whale evolution.
Answer:
Like starch, cellulose is a complex carbohydrate made up of many molecules of glucose linked together. But unlike starch, plants do not use cellulose to store energy. Instead, plants use cellulose as a structural molecule. It forms the cell wall that gives plant cells shape and support.
