The Lock-and-key mechanism was first proposed by Emil Fischer which described as the enzymatic reactions whereby an enzyme with a single substrate binds temporarily to form a substrate complex.
The lock-and-key mechanism is usually associated with the complementary shapes of an enzyme with a single substrate, wherein the lock that is being referred to is the enzyme and the substrate is the key. One right sized substrate (key) fits into the active site (key hole) of the enzyme (lock).
The active site which is mentioned above is structurally complementary to the substrate. This is the temporary binding site on the enzymes. Just like a lock and key, the enzyme as the lock and the substrate as the key is said to fit together.
Cellular organelles are the internal organs of a cell. They are responsible for keeping the cell alive. They do this by bringing in food for the cell, getting rid of waste, protecting and repairing the cell, and helping it grow/reproduce.
Progressive degeneration of the retina that affects night and peripheral vision is known as retinitis pigmentosa.
<h3>
What is retinitis pigmentosa?</h3>
- A collection of uncommon eye conditions known as retinitis pigmentosa affect the retina.
- Retinitis pigmentosa causes the retinal cells to gradually deteriorate over time, resulting in visual loss.
- RP is a hereditary condition that affects people at birth.
- The term "retinitis pigmentosa" (RP) refers to a group of illnesses that affect the retina's light-sensitive cells and impair vision.
- There is currently no medication to stop the course of the disease, nor is there a cure.
- Night blindness and tunnel vision are symptoms.
- Retinitis pigmentosa has no specific treatment.
- However, using UV sunglasses to protect the retina in your eyes may help postpone the onset of symptoms.
- For people with very advanced disease and severe visual loss, a retinal prosthesis (artificial retina) has been developed.

Answer:
ribosomes
Explanation:
ribosomes create proteins in the cell and could be considered a protien shake
Glucose is consumed and carbon dioxide is produced during the combined processes of glycolysis and cellular respiration.
Glucose is a simple sugar. Glucose is the most common monosaccharide, a type of carbohydrate. Glucose is primarily produced by plants and most algae during photosynthesis from water and carbon dioxide with the help of sunlight, where it is used to produce cellulose in cell walls, the world's most abundant carbohydrate.
A glucose molecule is gradually broken down into carbon dioxide and water during cellular respiration. Some ATP is produced directly along the way in the reactions that transform glucose. However, much more ATP is produced later in the process known as oxidative phosphorylation. The movement of electrons through the electron transport chain, a series of proteins embedded in the inner membrane of the mitochondrion, drives oxidative phosphorylation.
During glycolysis, a six-carbon sugar, glucose, undergoes a series of chemical transformations. It eventually degrades into two molecules of pyruvate, a three-carbon organic molecule. ATP is produced in these reactions.
