Answer: Proteins.
Explanation:
<u>Proteins are organic molecules made of amino acids</u> which are arranged in a linear chain and joined together through a peptide bond.
Membrane proteins are classified depending on their location:
- Integral membrane proteins are part of a cell membrane and can either penetrate the membrane or associate with one side of a membrane.
- Peripheral membrane proteins are transiently associated with the cell membrane.
They perform many important functions:
- Membrane receptor proteins: relay signals between the internal and external environments.
- Transport proteins: move molecules and ions across the membrane.
- Membrane enzymes: transform a molecule into another form
- Cell adhesion molecules: allow cells to identify each other.
Answer: Gene
Explanation:
Genes are the segment of DNA that are responsible for a particular trait in the body rising from their ability to code only a particular type of protein.
Genes are acquired from both parents during conception and are therefore the smallest unit in heredity.
Genes determine everything from the color of our eyes to the shape of our toes and are therefore very important in building life.
