How are cells specialized? correct answers through the process of differentiation or maturation What are the eight specialized cellular functions? correct answers movement, conductivity, metabolic absorption, secretion, excretion, respiration, reproduction, and communication What are the three general components of an eukaryotic cell? correct answers the plasma membrane, the cytoplasm, and the intracellular organelles. What causes the release of lysosomal enzemes? correct answers Cellular injury causing cellular self-digestion What is the location and function of the nucleus? correct answers the largest membrane-bound organelle and is found usually in the cell's center. The chief functions of the nucleus are cell division and control of genetic information. What is Cytoplasm? correct answers an aqueous solution (cytosol) that fills the space between the nucleus and the plasma membrane. What is the endoplasmic reticulum and what does it specialize in? correct answers a network of tubular channels (cisternae) that extend throughout the outer nuclear membrane. It specializes in the synthesis and transport of protein and lipid components of most of the organelles What is the Golgi complex and what does it do? correct answers a network of smooth membranes and vesicles located near the nucleus. The Golgi complex is responsible for processing and packaging proteins into secretory vesicles What are lysosomes and what do they do? correct answers saclike structures that originate from the Golgi complex and contain digestive enzymes. These enzymes are responsible for digesting most cellular substances to their basic form, such as amino acids, fatty acids, and carbohydrates What are peroxisomes? correct answers involved in the production and breakdown of hydrogen peroxide Importance of proteins in disease correct answers The major workhorses of the cell, if misfolded they can cause diseases What are mitochondria responsible for? correct answers . Mitochondria contain the metabolic machinery necessary for cellular energy metabolism (Makes ATP). What is the cytoskeleton? correct answers the "bone and muscle" of the cell. The internal skeleton is composed of a network of protein filaments, including microtubules and actin filaments (microfilaments).
