Enzymes – proteins that break molecules down to be absorbed by the body. If we didn’t have enzymes the metabolic process would happen too slowly and we would die.
Structural Proteins – strengthen cells. ( collagen makes up 25% of the body’s total protein, it strengthen bones and connective tissue)
Signaling Proteins – facilitate cellular communication. ( insulin is release in response to sugar consumption; it activates insulin receptors, which tell muscle and fat cells to store glucose)
Regulatory Proteins – bind DNA and determine gene expression. ( the p53 protein prevents cancer by preventing a cell from dividing when its DNA is damaged)
Transport Proteins – move nutrients around the body. ( hemoglobin receives oxygen from the lungs and transport it to all body cells)
Sensory Proteins – facilitate our five senses.
Motor Proteins – allow cells to move and change shape
Defense Proteins – vital part of the immune system. Help ward off infections and heal the body. ( antibodies are defense proteins which attach to pathogens 🦠, signaling they need to be killed)
Storage Proteins – store nutrients for later use
