Eukaryotic Cells
Which of the following organelles is surrounded by a single membrane?
A. Mitochondria
B. Ribosomes
C. Lysosome
D. Nuclei
C. Lysosome
What is false about prokaryotic cells?
A. They contain circular DNA
B. DNA replication occurs in the nucleus
C. They have flagella
D. They have a cell wall and a cell membrane
B. DNA replication occurs in the nucleus
Prokaryotes do not have a nucleus, but they contain a nucleoid region
The functional tissue of an organ is called:
A. Squamous epithelia
B. Parenchyma
C. Epithelial cells
D. Stratified epithelia
B. Parenchyma
An enzyme deficiency that results in the inability to break down hydrogen peroxide would most likely result in what?
A. Decreased function of the lysosome
B. Inability to break down long-chain Fatty-acids
C. Increased cellular pH
D. Decreased cellular pH
B. Inability to break down long-chain Fatty-acids
The question prompt scenario would affect the function of the peroxisome, leading to a buildup of long-chain FAs. The overcrowding of the FAs would displace the other cell compartments and eventually result in cell death.
Gram-negative and gram-positive cells differ in which way?
A. The presence of a peptidoglycan layer
B. The location of their peptidoglycan layer
C. The thickness of their peptidoglycan layer
D. The presence of a cell wall
C. The thickness of their peptidoglycan layer
Gram-negative cells have small amounts of peptidoglycan, which makes it unable to retain dye during a Gram-staining procedure
Epithelial tissue is most likely to be found in:
A. Body cavities
B. Lining organs
C. In muscles
D. A and B
E. B and C
D. A and B
What is the ribosomal subunit weight for a eukaryotic ribosome?
A.50S and 20S (70S)
B.60S and 20S (80S)
C.60S and 40S (80S)
D.50S and 30S (70S)
C. 60S and 40S (80S)
Which of the following is present in prokaryotic cells and eukaryotic cells?
A. ribosomes
B. Nucleus
C. Cell Wall
D. Flagella
A. ribosomes
Which of the following is not considered connective tissue?
A. Bone
B. Cartilage
C. Blood
D. They are all connective tissue
D. In addition to those, tendons, ligaments, and adipose tissue are connective tissues
