Smooth ER is part of the endomembrane system of the eukaryotic cell, and rough ER is not.

Plant and animal cells both carry out cellular respiration, producing ATPSelect the correct statement describing the cellular structure or function: Plant and animal cells both carry out cellular respiration, producing ATP. Only plant cells contain chloroplasts, and only animal cells contain mitochondria. Mitochondria and chloroplasts are part of the endomembrane system of the eukaryotic cell.
Products of the ER are usually modified during their transit from the CIS to the TRANS region of the Golgi ApparatusWhich statement correctly describes an endomembrane function? Products of the ER are usually modified during their transit from the CIS to the TRANS region of the Golgi Apparatus. The lumen of the endoplasmic reticulum (ER) is continuous with the cell nucleus. Secretory proteins in transit from one part of the cell to another are carried in lysosomes.
The cell cytoskeleton is a dynamic network of fibers that can be quickly dismantled and reassembled to change cell shape and the position of cell componentsChoose the best description of the cell cytoskeleton: The cell cytoskeleton is similar to an animal skeleton in providing rigid internal support and structure to the cell. The cell cytoskeleton serves as permanent scaffolding to anchor cell components into position within the cell cytoplasm. The cell cytoskeleton is a dynamic network of fibers that can be quickly dismantled and reassembled to change cell shape and the position of cell components.
Cell fractionation to study the function of specific organellesWhich of the following choices correctly matches a tool and its proper application? Transmission electron microscopy (TEM) to study the movement of organelles within a living cell. Scanning electron microscopy (SEM) to study the detailed movements of living cells. Light microscopy to study the internal structure of cilia. Transmission electron microscopy (TEM) to study the surfaces of preserved cells. Cell fractionation to study the function of specific organelles.
Whether or not the cell is partitioned by internal membranesWhich of the following clues would tell you if a cell is prokaryotic or eukaryotic? The presence or absence of a rigid cell wall. The presence or absence of ribosomes. Whether or not the cell contains DNA. Whether or not the cell carries out cellular respiration. Whether or not the cell is partitioned by internal membranes.
Central vacuole...storageWhich of the following correctly matches an organelle with its function? Nucleus...cellular respiration Central vacuole...storage Mitochondrion...photosynthesis Lysosome...movement Ribosome...manufacture of lipids
The nuclear envelope is continuous with the endoplasmic reticulumWhich statement correctly describes the nuclear envelope of a eukaryotic cell? The nuclear envelope is a single membrane, consisting of a phospholipid bilayer. Plasmadesmosomes in the nuclear envelope permit the exchange of macromolecules between the nucleus and the cytoplasm. All of the proteins of the cell are synthesized on ribosomes bound on the nuclear envelope. The nuclear envelope is continuous with the endoplasmic reticulum. The outer layer of the nuclear envelope is coated with laminin.
Proteins that will be secreted from the cell are likely to be found in closed spaces bounded by membranes of the endomembrane systemWhich one of the following statements about the endomembrane system is correct? Most of the phospholipids of the endomembrane system are synthesized in the mitochondria. The endoplasmic reticulum is continuous with the plasma membrane. Mitochondria function in the modification and sorting of lipids and proteins. Proteins that will be secreted from the cell are likely to be found in closed spaces bounded by membranes of be endomembrane system. Ribosomes move lipids and proteins among the different organelles of the endomembrane system.
Digestion of the food particle occurs in a vesicle enclosed by a membrane that separates the digestion from the cytoplasmA cell has formed a food vacuole as it ingested s food particle. Which of the following events is associated with the breakdown of that food particle? Proteins for digestion of the food particle were initially processed in mitochondria. Enzymes for the breakdown of the food are delivered to the food vacuole from the cytosol. Digestion of the food particle occurs in a vesicle enclosed by a membrane that separates the digestion from the cytoplasm. The membrane of the food vacuole is derived from the cell wall. Proteins for digestion of the food are made by ribosomes in the Golgi Apparatus.
Plant and animal cellsMitochondria are found in _____. Plants cells only Plant and animal cells Animal cells and prokaryotic cells, but not plant cells Animal cells only All cells

Movement of RNA molecules from the nucleus to the cytoplasmWhich of the following functions is NOT associated with the cytoskeleton in eukaryotic cells? Determining the shape of animal cells. The beating of cilia or flagella. Maintaining the position of the nucleus in the cell. The contraction of muscle cells in animals. Movement of RNA molecules from the nucleus to the cytoplasm.
Information can be transmitted from these extracellular structures to the cytoplasmWhich statement about extracellular structures (plant cell walls and the extracellular matrix of animal cells) is correct? Proteins and lipids are common components of extracellular structures. Extracellular structures store energy in the form of polysaccharides for subsequent metabolism by the cell. Information can be transmitted from these extracellular structures to the cytoplasm. All extracellular structures form barriers to separate adjacent cells. Extracellular structures regulate the passage of water molecules across the cell membrane.

Certain proteins are unique to each membraneIn what way do the membrane of a eukaryotic cell vary? Certain proteins are unique to each membrane. Some membranes have hydrophobic surfaces exposed to the cytoplasm, while others have hydrophilic surfaces facing the cytoplasm. Only certain membranes are constructed from amphipathic molecules. Phospholipids are found only in certain membranes. Only certain membranes of the cell are selectively permeable.
Embedded in a lipid bilayerAccording to the fluid mosaic model of membrane structure, proteins of the membrane are mostly: Confined to the hydrophobic interior of the membrane. Randomly oriented in the membrane, with no fixed inside-outside polarity. Free to depart from the fluid membrane and dissolve in the surrounding solution. Embedded in a lipid bilayer. Spread in a continuous layer over the inner and outer surfaces of the membrane.

A greater proportion of unsaturated phospholipids. A lower temperature. A greater proportion of relativity large glycolipids compared with lipids having smaller molecular masses. A relatively high protein content in the membrane.
Passive transportWhich of the following processes includes all others? Passive transport Diffusion of a solute across a membrane Transport of an ion down its electrochemical gradient Facilitated diffusion Osmosis
Decreasing extracellular pHBased on Figure 7.21 in your textbook, which of these experimental treatments would increase the rate of sucrose transport into the cell? Adding an inhibitor that blocks the regeneration of ATP. Decreasing cytoplasmic pH. Decreasing extracellular pH. Adding a substance that makes the membrane more permeable to hydrogen ions. Decreasing extracellular sucrose concentration.
The contents of a red blood cell are hypertonic to distiller waterWhich statement is correct? A solution of distiller water is hypotonic. A solution of seawater is hypertonic. The contents of a red blood cell are hypertonic to distiller water.
When a plant cell is placed in concentrated salt water, water moves out of the cell.Which of the following molecular movements is due to diffusion or osmosis? When a plant cell is placed in concentrated salt water, water moves out of the cell. Cells of the pancreas secret insulin into the bloodstream. The sodium-potassium pump pumps three sodium ions out of a neuron for every two potassium ions it pumps in.
