    What is chemiosmosis ?

    • Production of ATP "Citric Acid Cycle "

    • When a Phosphate bond breaks away from the Tri Phosphate molecule

    • The enzyme ATP Synthase sysnthesizes ADP to AMP

    • The enzyme ATP Synthase synthesizes ATP from ADP & Phosphate

    Correct Answer
    A. The enzyme ATP Synthase synthesizes ATP from ADP & Phosphate
    Explanation
    Chemiosmosis is the process by which ATP is synthesized in the mitochondria during cellular respiration. It involves the movement of protons (H+) across the inner mitochondrial membrane through ATP synthase, a protein complex. As the protons move through ATP synthase, it catalyzes the synthesis of ATP from ADP (adenosine diphosphate) and inorganic phosphate (Pi). This process is driven by the proton gradient established during the electron transport chain, where electrons are passed along a series of protein complexes, pumping protons from the mitochondrial matrix to the intermembrane space. The movement of protons back into the matrix through ATP synthase powers the synthesis of ATP.

    The break down of ATP UP happens in the

    • Stomach

    • Liver

    • Small intestine

    • Large intestine

    Correct Answer
    A. Small intestine
    Explanation
    ATP is broken down in the small intestine. This is because the small intestine is responsible for the digestion and absorption of nutrients from food. ATP, which is the energy currency of the body, is produced during cellular respiration in the mitochondria. When food is broken down in the small intestine, the nutrients are absorbed into the bloodstream. ATP is then produced from these nutrients in the cells of the body, including the small intestine itself. Therefore, the small intestine is the site where ATP breakdown occurs.

    The number of pyruvate molecules produced from 1 glucose molecule during glycolysis is

    • 4

    • 6

    • 2

    • 8

    Correct Answer
    A. 2
    Explanation
    During glycolysis, one glucose molecule is converted into two pyruvate molecules. This process occurs in the cytoplasm of the cell and is the first step in both aerobic and anaerobic cellular respiration. The conversion of glucose to pyruvate produces a small amount of ATP and NADH, which can then be used in subsequent steps of cellular respiration to generate more energy. Therefore, the correct answer is 2, as two pyruvate molecules are produced from one glucose molecule during glycolysis.

    For cellular reactions ATP produced moves out of the mitochondria

    • True

    • False

    Correct Answer
    A. True
    Explanation
    ATP is produced in the mitochondria through cellular respiration. Once produced, ATP molecules move out of the mitochondria and into the cytoplasm of the cell where they can be used as a source of energy for various cellular reactions. This movement of ATP out of the mitochondria allows it to be readily available for the cell's energy needs. Therefore, the statement "For cellular reactions ATP produced moves out of the mitochondria" is true.

    What are the causes of ATP depletion ?

    • Reduced supply of oxygen & nutrients/ Damage to mitochondria

    • Action of certain toxic chemicals/ Damage to mitochondria/ Reduced supply of CO2

    • Damage to mitochondria only.

    • Reduced supply of oxygen & nutrients/ Damage to mitochondria/Action of certain toxic chemicals

    Correct Answer
    A. Reduced supply of oxygen & nutrients/ Damage to mitochondria/Action of certain toxic chemicals
    Explanation
    The correct answer is that ATP depletion can be caused by a reduced supply of oxygen and nutrients, damage to mitochondria, and the action of certain toxic chemicals. These factors can all interfere with the normal functioning of mitochondria, which are responsible for producing ATP through cellular respiration. Reduced oxygen and nutrient supply can limit the availability of substrates needed for ATP synthesis, while damage to mitochondria can disrupt their ability to generate ATP. Additionally, certain toxic chemicals can directly inhibit ATP production or damage mitochondria, leading to ATP depletion.

    In the endothelium ATP binds to

    • P1 receptors

    • P2X receptors

    • P2Y receptors

    • P2Z receptors

    Correct Answer
    A. P2Y receptors
    Explanation
    ATP (adenosine triphosphate) is a molecule that can bind to various receptors in the endothelium. In this case, it specifically binds to P2Y receptors. P2Y receptors are a type of purinergic receptor that respond to ATP and other nucleotides. Activation of P2Y receptors in the endothelium can have various physiological effects, including regulation of blood flow, vascular tone, and inflammation. Therefore, P2Y receptors play an important role in mediating the effects of ATP in the endothelium.

    Endothelium Derived Relaxing Factor ( EDHF) has no role in vasodilation

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The statement "Endothelium Derived Relaxing Factor (EDHF) has no role in vasodilation" is false. EDHF is a key mediator in vasodilation, along with nitric oxide (NO) and prostacyclin (PGI2). It is released by endothelial cells in response to various stimuli, such as shear stress or agonists. EDHF acts on smooth muscle cells to induce relaxation and vasodilation, thereby regulating blood flow and blood pressure. Its mechanisms of action involve the activation of potassium channels and the production of hyperpolarizing factors. Overall, EDHF plays a crucial role in endothelium-dependent vasodilation.

    Exogenous administration of ATP will

    • Replace the metabolically generated ATP

    • Alter the metabolic reactions of ATP production

    • Not replace the metabolically generated ATP

    • Increase the ATP levels in the body significantly

    Correct Answer
    A. Not replace the metabolically generated ATP
    Explanation
    Exogenous administration of ATP will not replace the metabolically generated ATP because exogenous ATP is not efficiently taken up and utilized by cells. The body tightly regulates ATP levels through metabolic reactions, and exogenous ATP is typically broken down into its component parts before it can be used as an energy source. Therefore, the metabolically generated ATP remains the primary source of energy for cellular processes.

    Bioavailability of ATP can be measured only in

    • Atreolar portal blood

    • Pulmonary arteries

    • Venous portal blood

    • None of the options

    Correct Answer
    A. Venous portal blood
    Explanation
    The bioavailability of ATP refers to the amount of ATP that is available for use by cells. In this case, the question is asking where the measurement of ATP bioavailability can be done. The correct answer is venous portal blood. Venous portal blood refers to the blood that is returning from the organs and tissues to the liver through the hepatic portal vein. Since the liver is responsible for metabolizing ATP, measuring ATP bioavailability in venous portal blood would provide an accurate assessment of the amount of ATP available for cellular use.
