Cell Biology Questions

Mitochondria are found in __________.all cellsanimal cells onlyplant and animal cellsplant cells onlyanimal cells and prokaryotic cells but not plant cells

A cell with an abundance of free ribosomes is most likely carrying out which of the following processes?producing primarily vacuole contentsproducing primarily cell wall or extracellular matrix componentsproducing primarily proteins for secretionproducing primarily cytoplasmic proteinsproducing primarily an abundance of new membranes

Which one of the following statements about the endomembrane system is correct?Proteins that will be secreted from the cell are likely to be found in closed spaces bounded by membranes of the endomembrane system.The endoplasmic reticulum is continuous with the plasma membrane.Ribosomes move lipids and proteins among the different organelles of the endomembrane system.Most of the phospholipids of the endomembrane system are synthesized in the mitochondria.Mitochondria function in the modification and sorting of lipids and proteins.

Which of the following attributes is common to both prokaryotic cells and eukaryotic cells?A) the use of proteins as information storage moleculesB) the use of an external membrane to regulate the passage of materials from and to surroundingsC) a membrane-enclosed nucleusD) generally about the same sizemembrane-enclosed organelle

Which organelle occupies much of the volume of a PLANT cell?nucleusGolgi apparatusperoxisomemitochondrioncentral vacuole

The chemical reactions involved in respiration in prokaryotic and eukaryotic cells are virtually identical. In eukaryotic cells, ATP is synthesized primarily on the inner membrane of the mitochondria. In light of the endosymbiont theory for the evolutionary origin of mitochondria, where would you expect most ATP synthesis to occur in prokaryotic cells?on the plasma membranein the cytoplasmon the endoplasmic reticulumon the nucleoid membrane

All plant and animal cells carry out cellular respiration in mitochondria, producing ATP.TrueFalse

In a bacterium, where are proteins synthesized?ribosomes nucleus peroxisome nucleoid region capsule

Which of the following correctly matches an organelle with its function?ribosome ... manufacture of lipidsnucleus ... cellular respirationcentral vacuole ... storagelysosome ... movementmitochondrion ... photosynthesis

One difference between eukaryotic and prokaryotic cells is that eukaryotic cellsA) have membrane-enclosed organelles, which are lacking in prokaryotic cells.B) are enclosed by a membrane, which is lacking in prokaryotic cells.C) have DNA, which is lacking in prokaryotic cells.D) lack the complexity seen in prokaryotic cells.

What part of the cell functions in cellular respiration?

Select the correct statement describing cellular structure or function.A) Plant and animal cells both carry out cellular respiration, producing ATP.B) Only plant cells contain chloroplasts, and only animal cells contain mitochondria.C) Mitochondria and chloroplasts are part of the endomembrane system of the eukaryotic cell.

What is a function of a bacterium's capsule?DNA storage propulsion protein synthesisD) protection

What part of the cell functions in photosynthesis?

CHMwhat type of bond shares these characteristics? diatomic, noble gases, hydrocarbons (CH), symmetry (:), all outer elements are the same (C2H6)

Identify the correct statement about differences between rough and smooth endoplasmic reticulum (ER).Smooth ER is part of the endomembrane system of the eukaryotic cell, and rough ER is not.B) The outer surface of smooth ER lacks ribosomes, whereas the outer surface of rough ER has ribosomes.Rough ER consists of a network of membranous tubules and sacs called cisternae, whereas smooth ER is less complex.

What part of the cell functions in protein synthesis?

What part of the cell functions in synthesis of lipids, metabolism of carbohydrates, Ca2+ storage, and detoxification of drugs and poisons?

What part of the cell functions to give mechanical support to the cell and its organelles?

Which part of the cell contains most of the genetic material of the cell?
