Explanation:
The cell membrane is composed of a phospholipid bilayer.
The cell membrane is primarily composed of a mix of proteins and phospholipids
Phospholipids are a major component of cell membranes. They a head and a tail. The head is hydrophilic (attracted to water) and the tail is hydrophobic (repelled by water).
They form a bilayer in which their hydrophilic heads face the aqueous cytosol and extracellular fluid while their hydrophobic tails face away from the cytosol and extracellular fluid.
The lipid bilayer is semi - permeable
A. Proteins
B. Lipids
C. Nucleic acids
D. Carbohydrates
Enzymes are biomolecules that belong to proteins. They are vital for speeding up chemical reactions in the human body to ensure healthy living.
Enzymes are specialized biomolecules that play a fundamental role in the human body, primarily by speeding up chemical reactions critical for life. These biomolecules belong to the category of Proteins. This is because enzymes are composed of sequences of amino acids, which are the building blocks of proteins.
Unlike lipids, nucleic acids, and carbohydrates, proteins possess the unique ability to function as biological catalysts, reducing the amount of energy required for a reaction and thereby accelerating its rate.
