BIO 1201 GREGG CERTIFICATION TEST
PAPER COMPLETE QUESTIONS AND
SOLUTIONS FULLY VERIFIED
●● Ribosomes
Answer: complexes that make proteins; free in cytosol or bound to rough
ER or nuclear envelope
●● Golgi apparatus
Answer: active in synthesis, modification, sorting, and secretion of cell
products
●● Lysosome
Answer: digestive organelle where macromolecules are hydrolyzed, and
autophagy
●● Mitachondrion
Answer: organelle where cellular respiration occurs and most ATP is
generated
●● Cytoskeleton
,Answer: reinforces cell's shape; functions in cell movement; components
are made of protein. Includes: Microfilaments, Intermediate filaments,
Microtubules.
●● Endoplasmic Reticulum
Answer: network of membranous sacs and tubes; active in membrane
synthesis and other synthetic and metabolic processes; has rough
(ribosome-studded) and smooth regions
●● Rough ER
Answer: protein synthesis
●● Smooth ER
Answer: lipid synthesis
calcium ion storage
poison detoxification
●● Nucleolus
Answer: nonmembranous structure involved in production of ribosomes;
a nucleus has one or more nucleoli
●● Chromatin
Answer: material consisting of DNA and proteins; visible in a dividing
cell as individual condensed chromosomes
, ●● cell wall
Answer: outer layer that maintains cell's shape and protects cell from
mechanical damage; made of cellulose, other polysaccharides, and
protein
●● Chloroplast
Answer: photosynthetic organelle; converts energy of sunlight to
chemical energy stored in sugar molecules
●● central vacuole
Answer: prominent organelle in older plant cells; storage, breakdown of
waste products, hydrolysis of macromolecules; enlargement of vacuole
major mechanism of plant growth.
●● Part complete
The innermost electron shell of an atom can hold up to _____ electrons.
Answer: 2
●● Which of these relationships is true of an uncharged atom?
Answer: The number of protons is equal to the number of electrons
●● What determines the types of chemical reactions that an atom
participates in?
