NU 545 Chapter 01: Cellular Biology Test Bank Questions and Answer solutions with Rationales Already GRADED A 2024 UPDATE. What is differentiation or maturation? - ANS-Process by which cells become specialized. What are the eight specialized cellular functions? - ANS-Movement, conductivity, metabolic absorption, secretion, excretion, respiration, reproduction, and communication. What are the three general components of a eukaryotic cell? - ANS-Plasma membrane, cytoplasm, and intracellular organelles. What is the function of the nucleus? - ANS-Cell division and control of genetic information. What is cytoplasm? - ANS-Aqueous solution that fills the cytoplasmic matrix. What are organelles? - ANS-Structures suspended in the cytoplasm, enclosed in biological membranes. What is the function of the endoplasmic reticulum? - ANS-Synthesis and transport of protein and lipid components. What is the Golgi complex responsible for? - ANS-Processing and packaging proteins into secretory vesicles. What are lysosomes? - ANS-Sac-like structures that contain digestive enzymes. What do lysosomal enzymes do? - ANS-Digest most cellular substances to their basic form. What happens when there is cellular injury? - ANS-Release of lysosomal enzymes, causing cellular self-digestion. What are peroxisomes? - ANS-Organelles similar to lysosomes that contain enzymes using hydrogen peroxide. What is the function of mitochondria? - ANS-Contain enzymes for cellular energy metabolism and produce ATP. What is the cytoskeleton? - ANS-Internal skeleton of the cell composed of protein filaments.
