The given question is an example of a Chemical Reaction.
A Chemical Reaction can be defined as the process by which two or more substances interact with each other in such a way that a rearrangement of chemical bonds and molecular position occurs in them. This alteration in bonds and molecular position results in the formation of a new substance.
In a chemical reaction, the substances which are responsible for interacting with each other are called the Reactants.
In a chemical reaction, the new substances those are formed are called the Products.
A Chemical Reaction can be represented as follows:
W + X → Y + Z.
Here, W and X are reacting to form Y and Z.
So, W and X are the Reactants.
Y and Z are the Products.
As the Reactants react to form the Products, so the arrow → is represented from the Reactant to the Product.
In the given question,
glucose + fructose → sucrose + water
As arrow → always direct from Reactants to the Products, so the left side of the arrow will be the reactants and the right side of the arrow will be the products.
Hence, the Reactants are Glucose and Fructose.
The Products are Sucrose and Water.
So, Glucose and Fructose undergo chemical reaction to form Sucrose and Water.
Pepsinogen, an inactive zymogen, is secreted into gastric juice from both mucous cells and chief cells. Once secreted, pepsinogen is activated by stomach acid into the active protease pepsin, which is largely responsible for the stomach's ability to initiate digestion of proteins.
I just learned this in my previous lesson of biology. Endosymbiosis - a relationship between two organisms where one lives within another and both benefit.
