EXAM WITH CORRECT QUESTIONS
AND ANSWERS 2025
Nucleus - CORRECT-ANSWERSControl 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-ANSWERSCell work occurs here
Water, electrolytes, proteins, fats and glycogen
Cell Membrane - CORRECT-ANSWERSSeparates 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-ANSWERSSite of protein synthesis
Endoplasmic Reticulum - CORRECT-ANSWERSSystem of paired membranes
Rough and Smooth
Golgi Complex - CORRECT-ANSWERSModifies and packages substances from ER
Mitochondria - CORRECT-ANSWERSPower house of the cell (energy), also function to
regulate apoptosis
Lysosomes - CORRECT-ANSWERSMetabolism
Cytoskeleton - CORRECT-ANSWERSMicrotubules
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-ANSWERSThe basic fluid structure of the membrane and
serves as a semipermeable barrier.
Phospholipids with a hydrophilic head and a hydrophobic tail
Glycocalyx - CORRECT-ANSWERSParticipates in cell-to-cell recognition and adhesion.
Cell communication - CORRECT-ANSWERScellular, 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-ANSWERSRapid synaptic signaling
between electrically excitable cells
Transmission of impulses in nerve and muscle cells
G-Protein-Linked Receptors - CORRECT-ANSWERSThe on-off switch for signal
transduction
Enzyme-Linked Receptors - CORRECT-ANSWERSReceptors for certain protein
hormones
Activate an intracellular domain with enzyme activity
Intracellular Receptors - CORRECT-ANSWERSLigands move directly across the
membrane to bind to the intracellular receptor.
The Cell Cycle and Cell Division - CORRECT-ANSWERSMain stages of cell cycle (life
cycle of a cell)
Mitosis: cell division stage
Interphase: nondividing phase
Types of cell division
Mitotic cell division: occurs in somatic cells
