Week 3 Anatomy

QuestionAnswer
The inside of the cell is composed largely of a gel-like substance called cytoplasm.
Which area of the cytoplasm near the nucleus coordinates the building and breaking of microtubules in the cell? centrosome
Figure 2.1 Use the diagram above to answer the following questions. Which letter indicates the nucleolus? A
Which of the following is not a cytoskeleton element? centriole
Of the following, the only organelle that has a double membrane structure is the mitochondrion.
Often referred to as the “power plant” of the cell, which organelle is the site of ATP production? mitochondrion
Cisternae of this organelle are continuous with the nuclear envelope. rough endoplasmic reticulum
Figure 2.1 Use the diagram above to answer the following questions. Which letter indicates the Golgi apparatus? D
A spherical membrane-bound structure that contains the genetic material of the cell and is often referred to as the “command center” of the cell is the nucleus.
This organelle is primarily a sac of powerful digestive enzymes called acid hydrolas lysosome
Which of the following cytoskeleton elements are the largest in diameter? microtubules
This organelle is numerous in liver and kidney cells. peroxisome
Which of the following is a type of cell extension that lines the intestines and other areas of the body? microvilli
Figure 2.1 Use the diagram above to answer the following questions. Which letter indicates the mitochondrion? E
The plasma membrane is composed of all of the following except tubulin protein.
The outer boundary of a human cell is called the plasma membrane.
Figure 2.1 Use the diagram above to answer the following questions. Which letter indicates the plasma membrane? B
Which type of junction is formed when membrane channels of adjacent plasma membranes adhere to each other? gap junction
This membranous organelle is the site of protein synthesis for proteins that are secreted by the cell. rough endoplasmic reticulum
This organelle primarily modifies products from the rough ER, and it resembles a stack of hollow saucers, one cupped inside the next. Golgi apparatus
Figure 2.1 Use the diagram above to answer the following questions. Which letter indicates the rough endoplasmic reticulum? C
In the matrix of the plasma membrane, a variety of proteins are embedded. Some of these proteins serve as passageway for Na+ ions or glucose. These proteins are called transport proteins.
Ribosomes may be either free within the cytoplasm or bound to a membrane system known as the rough endoplasmic reticulum.
This organelle is characterized by folded membranes called cristae. mitochondria
This organelle has both a cis and a trans face. Golgi apparatus
Phospholipids of the plasma membrane are arranged as a bilayer with their nonpolar tails sandwiched between the polar heads.
Ribosomes are organelles that float in the cytoplasm and attach to the endoplasmic reticulum.
Which of the following statements about integral proteins in the plasma membrane is false? They are more abundant by volume than the membrane phospholipids.
This membranous organelle contains oxidase and catalase enzymes. peroxisome
A major function of the cell membrane is to control what enters and leaves the cell.
