Nursing 5003 Patho Practice Questions 2024. Oxidative phosphorylation occurs in the mitochondria and is the mechanism by which the energy produced from carbohydrates, fats, and proteins is transferred to ATP - ANSWER 1. What is the mechanism by which the energy produced from carbohydrates, proteins, and lipids is transferred to ATP as molecules that move from an area of high concentration to low concentration without the need of energy Cells can take in and use nutrients. - ANSWER Passive transport is best described by which statement? It binds water, cations (such as Ca2+, Na+ and K+), fatty acids, hormones, bilirubin, thyroxine (T4) and pharmaceuticals (including barbiturates): its main function is to regulate the Oncotic pressure of blood - ANSWER What is the role of Albumin Under anaerobic conditions the cells energy is produced by lactic acid fermentation by way of glycolysis. - ANSWER Under anaerobic conditions, which process provides energy for the cell? Receptors - ANSWER Neurotransmitters affect the postsynaptic membrane by binding to: Panacrine - ANSWER Which mode of chemical signaling uses local chemical mediators that are quickly taken up, destroyed, or immobilized? Hormonal-Hormonal signaling is any member of a class of signaling molecules produced by glands in multicellular organisms that are transported by the circulatory system to target distant organs to regulate physiology and behavior. - ANSWER Which mode of chemical signaling uses blood to transport communication to cells some distance away? The lipid bilayer with the hydrophilic head and hydrophobic tail keeps most water-soluble molecules from crossing the plasma membrane, but allows the fat-soluble molecules, such as oxygen and carbon dioxide through freely - ANSWER Which structure prevents water-soluble molecules from entering cells across the plasma membrane? Proteins- transporter proteins or membrane transport proteins. Their mechanism of action includes active transport and facilitated diffusion. - ANSWER Which organic compounds facilitate transportation across the cell membrane by acting as receptors, transport channels for electrolytes, and enzymes to drive active pumps?
