- It is true that a eukaryotic cell:
○ Is smaller than a prokaryotic cell.
○ Contains structures called organelles.
○ Lacks a well-defined nucleus.
○ Does not contain histones.
Eukaryotes are large, have membrane-bound intracellular compartments called organelles, has
a well defined nucleus, and have histones. - The function of a histone found in a eukaryote cell focuses on cellular:
○ Division
○ Movement
○ Activities
○ Deoxyribonucleic acid (DNA) folding
These proteins bind DNA and are involved in supercoiling of DNA. - An organelle that is responsible for the metabolism of cellular energy is referred to as
a/an:
○ Golgi complex
○ Mitochondrion
○ Endoplasmic reticulum
○ Nucleolus
Organelle found in large numbers and is responsible for cellular respiration and energy
production. Mitochondria contain their own DNA that codes for enzymes needed for oxidative
phosphorylation. - Which statement best describes a desmosome?
○ A desmosome is a barrier to diffusion.
○ Desmosomes hold cells together by continuous bands.
○ A desmosome is a communicating tunnel.
○ Desmosomes function as a zona occludens.
Desmosomes hold cells together by forming either continuous bands or belts of epithelial sheets
or button-like points of contact. Desmosomes also act as a system of braces to maintain
structural stability. - Which statement describes the function of a second messenger?
○ Extracellular ligand that binds with membrane-bound receptors
○ Intracellular enzyme that once will trigger a cascade of intracellular events
○ Chemical messenger that opens specific channels in the cell membrane
○ Chemical messenger that blocks a membrane-bound receptor signal
