Three characteristics of enzymes​

Biology
1 answer:
levacccp [35]3 years ago

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.

harina [27]
<span><span>anonymous </span> 3 years ago</span>Proteins are involved in almost all of the cell's functions. They can act as: Transportation: they can transport hydrophobic molecules in blood for example Regulation: protein hormones and enzymes Receptor: can act as receptors on cell surface and in the subsequent signal transduction (G-protein for instance) It is true that all proteins are made up of up to 20 amino acids, but there are several reasons for their diverse actions: -One reason is the possible sequence and number of amino acids: Met-Ser-His is different from Met-His-Ser for example. Besides, you have different chain length, for a protein is made up of long chain of polypeptide (longer than 50-70 amino acids) and can have any of the 20 amino acids with repetition, so using simple probability, this can provide up to practically unlimited combination with proteins that have chains of thousands of amino acids. -Another very crucial reason for the diversity of protein action is the conformation. A protein passes by at least 3 conformational stages before becoming mature. The straight amino acid chain is the primary structure of the protein that can never be active. Spatial modification of this primary structure results in a secondary structure, Helix or Beta-pleated sheets (or other coiling structure), that is also inactive. Further coiling and bending of the secondary structure produce a 3-dimentional conformation that is the active form of the protein. Moreover, many proteins can undergo further conformational rearrangement and combination with other protein sub-units producing a quaternary structure.

kupik [55]

Answer:

In the absence of sunlight the plants which are dependent on sunlight for making food that is photosynthesis would die.

Also the people will suffer as sunlight is a good source of Vitamin D and in absence of sunlight they will not get it so easily.
