Openstax Anatomy and Physiology
Chapter 3 Questions and Correct
Answers
Question: Active Transport
Answer: Form of transport across the cell membrane that requires input
of cellular energy
Question: Amphipathic
Answer: Describes a molecule that exhibits a difference in polarity
between its two ends, resulting in a difference in water solubility
Question: Anaphase
Answer: Third stage of mitosis (and meiosis), during which sister
chromatids separate into two new nuclear regions of a dividing cell
Question: Anticodon
Answer: Consecutive sequence of three nucleotides on a tRNA molecule
that is complementary to a specific codon on an mRNA molecule
Question: Autolysis
Answer: Breakdown of cells by their own enzymatic action
Question: Autophagy
Answer: Lysosomal breakdown of a cell's own components
Question: Cell Cycle
Answer: Life cycle of a single cell, from its birth until its division into two
new daughter cells
Question: Cell Membrane
Pretest - Stuvia US
, 2
Answer: Membrane surrounding all animal cells, composed of a lipid
bilayer interspersed with various molecules; also known as plasma
membrane
Question: Centriole
Answer: Small, self-replicating organelle that provides the origin for
microtubule growth and moves DNA during cell division
Question: Centromere
Answer: Region of attachment for two sister chromatids
Question: Centrosome
Answer: Cellular structure that organizes microtubules during cell division
Question: Channel Protein
Answer: Membrane-spanning protein that has an inner pore which allows
the passage of one or more substances
Question: Checkpoint
Answer: Progress point in the cell cycle during which certain conditions
must be met in order for the cell to proceed to a subsequence phase
Question: Chromatin
Answer: Substance consisting of DNA and associated proteins
Question: Chromosome
Answer: Condensed version of chromatin
Question: Cilia
Answer: Small appendage on certain cells formed by microtubules and
modified for movement of materials across the cellular surface
