<h2>Tropomyosin</h2>
Explanation:
This protein is most likely: Tropomyosin.
Sacromere is the structural unit of myofibrils i.e. the fibres of the muscles.
Tropomyosin is the muscle protein that function in contraction of muscle filaments.They are arranged laterally along the myofilament. When the researcher is observing the sacromere, she is observing the muscle fibre. So, the protein that lines the periphery along the thin filament is more likely to be tropomysin.
Answer:
Explanation:
Molecular Transport - Proteins are used to move small molecules such as calcium, potassium, and sodium ions across the membrane. - cell takes in large particles by engulfing them. Phagocytosis - "cell eating" - extensions off cytoplasm surround a particle and package it within a food vacuole and then the cell engulfs it.
