Differentiates between respiration and breathing |
|
|
Answer» Respiration which realeased energy and breathing is a process which absorbed oxygen and released carbon dioxide | \tBreathing involves the process of inhaling and exhaling the air in and out of lungs. While breathing, oxygen is inhaled and carbon dioxide is exhaled.Respiration is the process of the breaking down the glucose to produce energy which is used by cells to carry out the cellular function.Breathing takes place in lungs.Respiration takes place in cells.Breathing is a physical voluntary process.Respiration is a chemical involuntary process.No energy is produced during the process.Energy is released in the form of ATP.It is an extracellular process, as it occurs outside cells.It is an intracellular process, as it occurs inside cells.No enzymes are used during the process.A large number of enzymes are used during the process.Breathing takes places through respiratory organs like lungs, nose, etc.Respiration takes place in cells and cell organelles like mitochondria, etc.\t | |

Definetion of chemical equation |
|
Answer» Chemical equations are the symbolic representation of chemical reactions The symbolic representation of a chemical reaction is called a chemical equation.Features of a chemical equation:\tThe reactants are written on the left hand side with a plus sign between them.\tThe products are written on the right hand side with a plus sign between them.\tAn arrow separates the reactants from the products. The arrow head points towards the products and indicates the direction of the reaction. Representation of a chemical reaction with the help of symbols and formulae of substance involved in it is known as chemical equation. A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and formulae, wherein the reactant entities are given on the left-hand side and the product entities on the right-hand side. |
