The sodium-potassium pump requires energy to move sodium and potassium ions across the cell membrane. Which of these describes the process used by the sodium-potassium pump?
-
Osmosis
-
Diffusion
-
Active transport
-
Photosynthesis
Correct Answer
A. Active transportExplanation
The sodium-potassium pump uses active transport to move sodium and potassium ions across the cell membrane. Active transport is a process that requires energy to move substances against their concentration gradient, from an area of lower concentration to an area of higher concentration. In this case, the pump moves sodium ions out of the cell and potassium ions into the cell, creating an electrochemical gradient. This process is essential for maintaining the proper balance of sodium and potassium ions inside and outside the cell.Rate this question:

Active transport moves molecules from a low concentration to a high concentration.
-
True
-
False
Correct Answer
A. TrueExplanation
Active transport is a process that requires energy to move molecules against their concentration gradient, from an area of low concentration to an area of high concentration. This process is essential for maintaining proper cellular function and allows cells to accumulate molecules or ions that are needed in higher concentrations inside the cell. Therefore, the statement that active transport moves molecules from a low concentration to a high concentration is correct.Rate this question:

The difference in the concentration of a substance from one location to another is called
-
Diffusion
-
Concentration gradient
-
Osmosis
-
Passive transport
Correct Answer
A. Concentration gradientExplanation
The correct answer is concentration gradient. This term refers to the difference in the concentration of a substance between two locations. It is a measurement of how much the concentration of a substance changes over a given distance. This difference in concentration is important because it drives processes such as diffusion and osmosis, which rely on the movement of molecules from areas of high concentration to areas of low concentration. Passive transport is a broader term that encompasses these processes, but concentration gradient specifically refers to the difference in concentration.Rate this question:

What is the function of the proteins in the cell membrane?
-
Cellular respiration
-
Cell transport
-
Photosynthesis
-
Communication
Correct Answer
A. Cell transportExplanation
Proteins in the cell membrane play a crucial role in cell transport. They act as transport channels and carriers, allowing the movement of molecules and ions across the membrane. These proteins facilitate the import and export of essential substances, such as nutrients and waste products, in and out of the cell. Additionally, they also help in the regulation of cell volume and maintain the balance of ions inside and outside the cell. Therefore, the function of proteins in the cell membrane is primarily associated with cell transport.Rate this question:

When cells take in food particles through active transport, what is it called?
-
Exocytosis
-
Pinocytosis
-
Osmosis
-
Phagocytosis
Correct Answer
A. PhagocytosisExplanation
Phagocytosis is the process by which cells engulf and take in solid particles or large molecules. It is a form of active transport where the cell membrane extends and surrounds the particle, forming a vesicle called a phagosome. This process is commonly observed in immune cells, such as macrophages, which engulf and destroy foreign substances, pathogens, or cellular debris. Therefore, phagocytosis is the correct answer for the given question.Rate this question:

The movement of oxygen into a cell until equilibrium is reached without the use of ATP is an example of:
-
Active transport
-
Osmosis
-
Passive transport
-
Oxidative transport
Correct Answer
A. Passive transportExplanation
Passive transport is the correct answer because it refers to the movement of substances across a cell membrane without the use of ATP, which is the energy currency of the cell. In this case, oxygen is moving into the cell until equilibrium is reached, meaning there is no net movement of oxygen. This process occurs spontaneously and does not require any energy input from the cell. Therefore, it is an example of passive transport.Rate this question:

When cells take in a liquid through active transport, what is it called?
-
Exocytosis
-
Phagocytosis
-
Pinocytosis
-
Osmosis
Correct Answer
A. PinocytosisExplanation
Pinocytosis is the process by which cells take in a liquid through active transport. This process involves the formation of small vesicles or pockets in the cell membrane that engulf the liquid and bring it into the cell. Unlike exocytosis, which is the process of releasing substances from the cell, pinocytosis is a way for cells to take in fluids and dissolved substances from their surroundings. Phagocytosis, on the other hand, is the process of engulfing and digesting solid particles, while osmosis is the passive movement of water across a membrane.Rate this question:

This is the process that creates glucose using energy from the sun in animal cells.
-
Photosynthesis
-
Cellular respiration
-
Protein synthesis
-
No such process exists.
Correct Answer
A. No such process exists.Explanation
The given question states that this process creates glucose using energy from the sun in animal cells. However, it is a well-known fact that animals do not possess the ability to undergo photosynthesis, which is the process by which plants convert sunlight into glucose. Therefore, the correct answer is that no such process exists in animal cells.Rate this question:
