The activation energy needed for the chemical reaction decreased by an Enzyme.
Activation energy is the amount of energy required in a chemical reaction.
Enzymes lowers the activation energy by increasing the rate of reaction.
The energy required for a reaction to start is called activation energy. Enzymes are proteins that lower the activation energy of a reaction. In doing this, enzymes increase the rate of a reaction, helping it to occur faster. However, enzymes are not consumed in a reaction; they simply help it to occur.
Answer:
The cell theory was given by Schwann and Schleiden. The fact that cells can be observed in plants, animals, fungi, protists, bacteria and archea comes from one of the postulates of cell theory- All living organisms are composed of one or more cells.
Explanation:
The cell theory initially contained three postulates:
- The cell is the basic unit of organization in all organisms.
- All living organisms contain one or more than one cell.
- All cells arise from cells which are already in existence.
The discovery of cell was made by Robert Hooke. Later after further observations, more points were added to the cell theory like
- The genetic component of the cell is DNA and is transferred within cells.
- The <em>chemical composition</em> of all the cells is similar.
- A flow of <em>energy</em> occurs within the cells.
<span>The nucleolus is the structure within the nucleus of eukaryotic cells. It consists of RNA, DNA, and proteins. The nucleolus is involved in ribosome biogenesis which results in the synthesis of ribosomes. Ribosomal RNA (rRNA) is transcribed from DNA in the nucleolus. rRNA is processed into three mature RNAs and together with proteins form ribosomal subunits. After subunits form the ribosomes, they are transported out of the nucleus to the cytoplasm where they take place in translation.</span>
