2026
Nucleus correct answer Control center of the cell, which is vital
for protein synthesis
Control center
Contains all the cell DNA (except for DNA in mitochondria)
Nuclear envelope
Nuclear pores
DNA
Chromatin (condenses into chromosomes during prophase of
mitosis)
RNA synthesis
Messenger
Ribosomal
Transfer
Nucleolus
Cytoplasm correct answer Cell work occurs here
,Water, electrolytes, proteins, fats and glycogen
Cell Membrane correct answer Separates intracellular and
extracellular environments
Provides receptors for hormones and other substances
Electrical activity between nerve and muscle cells
Aids in cell growth/proliferation
Provides receptors for hormones and other biologically active
substances
Participates in the electrical events that occur in nerve and
muscle cells
Aids in the regulation of cell growth and proliferation
Ribosomes correct answer Site of protein synthesis
Endoplasmic Reticulum correct answer System of paired
membranes
Rough and Smooth
Golgi Complex correct answer Modifies and packages
substances from ER
Mitochondria correct answer Power house of the cell (energy),
also function to regulate apoptosis
,Lysosomes correct answer Metabolism
Cytoskeleton correct answer Microtubules
Develop and maintain cell form
Participate in intracellular transport mechanisms
Form basic structure for complex cytoplasmic organelles
Contain cilia and flagella
Contain centrioles and basal bodies
Produce muscle contraction (actin and myosin)
Support and maintain the asymmetric shape of cells
Are thin threadlike cytoplasmic structures
Categorized as thin, intermediate, and thick myosin
Lipid bilayer correct answer The basic fluid structure of the
membrane and serves as a semipermeable barrier.
Phospholipids with a hydrophilic head and a hydrophobic tail
Glycocalyx correct answer Participates in cell-to-cell
recognition and adhesion.
Cell communication correct answer cellular, tissue, organ, and
system communication is an essential component of homeostasis
(function and growth).
, Autocrine signaling occurs when a cell releases a chemical into
the extracellular fluid that affects its own activity.
Paracrine signaling acts on nearby cells.
Endocrine signaling relies on hormones carried in the bloodstream
to cells throughout the body.
Synaptic signaling occurs in the nervous system, where
neurotransmitters act only on adjacent nerve cells.
Ion-Channel-Linked Receptors correct answer Rapid synaptic
signaling between electrically excitable cells
Transmission of impulses in nerve and muscle cells
G-Protein-Linked Receptors correct answer The on-off switch
for signal transduction
Enzyme-Linked Receptors correct answer Receptors for certain
protein hormones
Activate an intracellular domain with enzyme activity
Intracellular Receptors correct answer Ligands move directly
across the membrane to bind to the intracellular receptor.
