Amoeba Sisters Short: Roles of Proteins

Introduction

• Discussion on the various roles of proteins
• Mention of food sources that provide proteins: beans, meat, nuts, eggs

Amino Acids and Protein Synthesis

• Proteins are composed of amino acids, which are their building blocks
• Proteins synthesized from amino acids

Muscle Function

• Common association of proteins with muscles
• Key proteins involved: actin, myosin
• Role in muscle contraction and structure

Hormones

• Some hormones are proteins, e.g., insulin

Enzymes

• Most enzymes are proteins
• Role in metabolic processes: building up or breaking down substances

Cell Membrane Functions

• Proteins as channels or pumps
• Assist in moving substances across cell membranes

Cell Signaling

• Proteins as receptors critical for cell signaling
• Importance in coordinating cellular actions

Immune System

• Antibodies are proteins produced by B cells
• Role in defending the body as part of the immune system

Structural Proteins

• Proteins form various structures, e.g., hair, collagen

Conclusion

• Proteins have diverse and critical roles beyond muscle-related functions
