  • 2. 

    Many gland cells release their secretions by means of ___.

    • Exocytosis

    • Phagocytosis

    • Receptor-mediated endocytosis

    • Fluid-phase pinocytosis

    • Cytokinesis

    Correct Answer
    A. Exocytosis
    Explanation
    Exocytosis is the process by which gland cells release their secretions. During exocytosis, secretory vesicles fuse with the cell membrane, allowing the contents of the vesicles to be released into the extracellular space. This mechanism is commonly used by various gland cells, such as those in the salivary glands, pancreas, and sweat glands, to release hormones, enzymes, and other substances into the body. Exocytosis is a vital process for maintaining homeostasis and regulating various physiological functions.

    There is a higher concentration of potassium inside the cell than outside the cell because of 

    • Facilitated diffusion.

    • Exocytosis.

    • Endocytosis.

    • Osmosis.

    • Sodium-potassium pump.

    Correct Answer
    A. Sodium-potassium pump.
    Explanation
    The sodium-potassium pump is responsible for maintaining the higher concentration of potassium inside the cell compared to outside the cell. This pump actively transports potassium ions into the cell and sodium ions out of the cell, against their concentration gradients. This process requires energy in the form of ATP. Facilitated diffusion, exocytosis, endocytosis, and osmosis do not directly contribute to the higher concentration of potassium inside the cell.

    The movement of oxygen from the alveoli of the lungs into the bloodstream is an example of 

    • Diffusion.

    • Osmosis.

    • Active transport.

    • Bulk transport.

    • Facilitated diffusion.

    Correct Answer
    A. Diffusion.
    Explanation
    The movement of oxygen from the alveoli of the lungs into the bloodstream occurs through diffusion. Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration. In this case, oxygen molecules move from the alveoli, where there is a higher concentration of oxygen, to the bloodstream, where there is a lower concentration of oxygen. This movement occurs passively, without the need for energy or a transport protein, making diffusion the correct answer.

  • 5. 

    If a cell is placed in a hypotonic solution, it

    • Will swell

    • Will shrink

    • Will stay the same size

    • May swell, shrink or stay the same size, depending upon the concentration of the solution

    Correct Answer
    A. Will swell
    Explanation
    When a cell is placed in a hypotonic solution, it means that the concentration of solutes outside the cell is lower than inside the cell. As a result, water will move into the cell through osmosis, causing the cell to swell. The water moves from an area of lower solute concentration (outside the cell) to an area of higher solute concentration (inside the cell) in order to equalize the concentration on both sides of the cell membrane. Therefore, the correct answer is that the cell will swell.

    Aerobic cellular respiration

    • Occurs in the mitochondria.

    • Produces ATP.

    • Uses oxygen.

    • All of these choices are correct.

    Correct Answer
    A. All of these choices are correct.
    Explanation
    Aerobic cellular respiration is a process that occurs in the mitochondria of cells. It involves the breakdown of glucose to produce ATP, which is the main source of energy for cellular activities. This process requires oxygen as the final electron acceptor in the electron transport chain. Therefore, all of the given choices are correct as they accurately describe different aspects of aerobic cellular respiration.

    Diffusion

    • Depends upon a concentration gradient

    • Results in net movement of molecules from regions of low concentration to regions of high concentration

    • Is important for moving molecules over large distances in the body

    • Requires energy in the form of ATP to be carried out

    • Includes all of the choices

    Correct Answer
    A. Depends upon a concentration gradient
    Explanation
    Diffusion is the movement of molecules from an area of high concentration to an area of low concentration. It occurs due to the concentration gradient, which is the difference in concentration between two areas. The molecules move passively, meaning no energy is required for diffusion to occur. Therefore, the correct answer is "Depends upon a concentration gradient."

  • 8. 

    Transcription involves _________, translation involves _______.

    • Protein synthesis; mRNA synthesis

    • MRNA synthesis; protein synthesis

    • DNA replication; mRNA synthesis.

    • Amino acids; nucleotides

    Correct Answer
    A. MRNA synthesis; protein synthesis
    Explanation
    Transcription is the process by which an mRNA molecule is synthesized from a DNA template. This involves the production of an mRNA molecule that carries the genetic information from the DNA to the ribosomes. On the other hand, translation is the process by which the mRNA molecule is used as a template to synthesize a protein. During translation, the ribosomes read the genetic code carried by the mRNA and assemble the corresponding amino acids to form a protein. Therefore, the correct answer is mRNA synthesis; protein synthesis.

    The red blood cells do not contain mitochondria, so these cells cannot

    • Produce any ATP.

    • Use glucose.

    • Produce enzymes.

    • Produce much ATP.

    • Divide.

    Correct Answer
    A. Produce much ATP.
    Explanation
    Red blood cells do not contain mitochondria, which are responsible for producing ATP, the energy currency of the cell. Therefore, red blood cells cannot produce a significant amount of ATP compared to other cells in the body.

    Rate this question:

  • 10. 

     The majority of ATP produced by a cell is produced as the result of

    • Glycolysis

    • Krebs (citric acid) cycle

    • Lactic acid

    • Electron transport system

    • All of the above

    Correct Answer
    A. Electron transport system
    Explanation
    The majority of ATP produced by a cell is produced as the result of the electron transport system. This process occurs in the inner mitochondrial membrane and involves the transfer of electrons from electron carriers to oxygen, creating a proton gradient. This gradient is then used by ATP synthase to generate ATP through oxidative phosphorylation. Glycolysis and the Krebs cycle also contribute to ATP production, but they produce a smaller amount compared to the electron transport system. Lactic acid fermentation is an alternative pathway that occurs in the absence of oxygen and does not produce ATP efficiently.
