. ATP is being rapidly consumed near the cellular membrane. Take up the quiz below and get to see how much you understood its structure and how it helps it attain its functions. 1 Which of the following statements best describes a characteristic feature of integral membrane proteins.

A compartment that contains DNA and regulates when genes are turned on and off. 3 It has the same permeability to all substances found inside or outside the cell. This CH2 molecular structure contained a negatively charged phosphate group.

The protective outer layer that controls what enters and leaves the cell. It contains the genetic information needed for protein production. Describe the structure and function of major and subcellular organelles such as the nucleus cell membrane mitochondria chloroplast etc.

Across the cell membrane to an area of high concentration. Which statement best describes the plasma membrane of a living plant cell. O D It allows substances to freely enter and exit the cell.

Provides mechanical shape C. Choose the statements that best describe the cell theory. O A It controls which substances enter and exit the cell.

A cell engulfs a particle by wrapping pseudopodia around it and packaging it within a vacuole. A small compartment that includes a cytoplasm a nucleus and a cell membrane. All iving things are made of cells and cells come only from pre-existing cells.

Responsible for the synthesis of ATP. 2Resolving power is the A ability of an optical instrument to show two close objects as separate B size. What statement best describes a cell membrane a Its found only in animal cells b Its a nonliving structure c It controls reproduction in the cell d it controls passage of materials into the cell was asked on May 31 2017.

A typical animal cell comprises the following cell organelles. B They are hydrophobic. Which of the following statements accurately describes why an animal cell would be surrounded by an extra cellular matrix instead of a cell wall.

The secretion of neurotransmitters out of the nerve cell from small vesicles at the end of the axon can be considered an example of _____. Its primary role is to protect the cell from its surrounding. Which statement best describes how osmosis will affect this animal cell.

Asked by Shorlock Last updated. Regulates passage of molecules into and out of the cell D. Provides mechanical strength B.

Which statement best describes phagocytosis. A Cells use this process to export products such as insulin or thyroxine. 1Which of the following is NOT a characteristic of an animal plasma membrane.

A sac-like membrane that stores water. A thin semipermeable membrane layer of protein and fats surrounding the cell. Lesson 11 The Cell Theory By definition a cell is the integral and structural unit of all living organisms.

Does the fluid mosaic model describe the plasma membrane as a structure that is liquid and very rigid. O C It prevents substances from entering the cell. A folded membrane that moves materials around inside cells Also acts as the site of manufacturing materials needed by the cell.

This is because there are proteins inside the cell membrane that help stop things from getting in that arent supposed to but are small enough to get through unassisted and because there are proteins embedded in the outer and inner. The two major components of the cell membrane are. 1 It selectively regulates the passage of substances into and out of the cell.

Stores information on DNA molecules Directs and controls the activities of the cell. Which statement best describes the primary function of the CH2 and phosphate molecular structure located in the plasma membrane. Cells come only from pre-existing cells.

C A receptor on the plasma membrane binds to a molecule and the cell engulfs both the receptor and the molecule. Also it controls the entry and exit of nutrients and other microscopic entities into the cell. Which statement best describes phagocytosis.

Cells must be clumped D. Plasma membrane of an animal cell. Allving things are made of cells.

The membrane proteins help in transportation of water ions and solute across the membrane and thus provide semi permeability to the membrane. Substances are moving through channels in the cell membrane. The cell membrane therefore has two functions.

It is the smallest biological structural and functional unit of all plants and animals. B Small droplets of extracellular fluid and all the dissolved solutes enter the cell by this process. 4 It is a double protein layer with floating lipid molecules.

The plasma membrane allows waste products to exit the cell and nutrients to enter the cell. Substances are moving from high to low concentrations. 2 It is composed of proteins and carbohydrates only.

First to be a barrier keeping the constituents of the cell in and unwanted substances out and second to be a gate allowing transport into the cell of essential nutrients and movement from the cell of waste products. A They are hydrophilic. It is composed of phospholipid bilayer structure with embedded proteins.

Which of the following statements best describes the function of the cell membrane. Substances are moving rapidly across the cell membrane. Plasma membrane is the outer covering of all the cells but only in a plant cell it is present below the cell wall.

Proteins embedded in two layers of phospholipidWith the proteins embedded in the plasma membrane the cell retains its general restriction for polar molecules crossing the membrane but the proteins provide for selective transport functions. O B It prevents substances from leaving the cell. Which of these statements best describes the function of the cell.

The cell membrane controls the movement of substances in and out of cells and organelles while protecting the cell from its surrounding. C They are amphipathic with at least one hydrophobic region. View the answer now.

The smallest structural and functional unit of an organism that can be said to be alive. Which best describes the structure of a cells plasma membrane. This process is called ___.

An animal cell placed in a sugar solution is shown in the diagram.
