Enzymes are biological catalysts. They speed up reactions although they are not changed in the reaction. Enzymes are proteins, and therefore are folded chains of amino acids with a specific shape. This shape is determined by the sequence of amino acids held together by bonds, for example Hydrogen bonds. Enzymes speed up reactions by bringing reactants together and reducing the activation energy required to start the reaction (enzymatic reaction).
Enzymes are specific: they have a specific shape, therefore only a certain substrate will fit its active site. There are two theories of enzyme action: Lock and Key and Induced Fit. The lock and key theory states that only a certain substrate will fit a certain active site, just like a key fits a lock. Induced Fit, likewise, states that enzymes wrap around substrates, attracted to each other by opposite charges, forming an enzyme substrate complex.
All of the work being done in side of a cell is being done by enzymes. A bacterial like E.coli has about 1,000 enzymes floating in the cytoplasm at about any time. The purpose of a enzyme in a cell is to allow the cell to carry out any chemical reactions very quickly. the reactions allow the cell to build or take things apart as needed. This is how the cell grows and reproduces. Hopefully my answer helps a little!
Yes it's true. i can explain it with very consiously but i am going to bed now
Answer:
resistors, transistors, capacitors, inductors, and diodes.
Explanation:
One of the challenges that scientists face when classifying a new fossil is that any tiny detail is all that separates one species from another. Further exploration is required to identify another set of characteristics that may help in deciding which organism belongs or create a new class.
