<span>Active transport is the movement of molecules across a cell membrane from a region of their lower concentration to a region of their higher concentration—in the direction against some gradient or other obstructing factor (often a concentration gradient).</span>
Molecules that have the same chemical formula but have different molecular structures are: Isomers.
The change in chemical composition of interstitial fluid affects the oxygen and nutrients transportation to the cell, and also removal of waste from the cell.
Interstitial fluid- Extracellular fluid is mostly made up of blood plasma and interstitial fluid. Interstitial fluid is the substance that fills the spaces between cells. Salts, water, cellular waste products, coenzymes, hormones, carbohydrates, fatty acids, and amino acids make up its composition.
Chemical Composition- The chemical composition of a material refers to the configuration, proportion, and kind of atoms in chemical substance molecules. The chemical makeup will alter when substances interact. For instance, when hydrogen and oxygen combine, water is produced.
