Question

Cell communicate by displaying plasma membrane receptor on the surface of the membrane they use receptor proteins inside the target cell they form protein channels that coordinate the activities of the adjacent cell a and b are correct only a, b, and c are all correct Among the modes of chemical signaling by cells paracrine signaling involves secreting a substance that bind to a target cells nearby secreting a sentence that can affect the cell that produced it secreting a substance that will have no effect on any cell neither of these answer is correct All of the chemical tasks of maintaining essential cellular functions are referred to as ___________. metabolic pathway metabolism catabolism anabolism Among the phases of cellular catabolism, most of the ATP is generated during which phase? digestion glycolysis oxidation citric acid cycle Match definition with terms: Algor mortis hypoxias cause by ischemia Rigor moris tuberculous pulmonary infection Somatic death cessation of respiration and circulation Caseous necrosis reduction body temperature Coagulative necrosis gravity causes blood to settle to lowest tissue Tonicity is important especially for red blood cells When the osmolality of extracellular fluid is greater 285 mOsm/kg, the extracellular can be considered as ______. hypotonic hypertonic isotonic neither a, b, or c is correct A nurse analysed the chromatin material of somatic cells and found that there was the normal numbers of chromosome in the nucleus It can be said that these cells are haploid cell dipoid cells polypoid cells euploid cell A nurse analyzed the chromatin material of somatic cells and found that these somatic cells had 1 extra copy of chromosomes. It can be said that these cells are ________ diploidy triploidy euppoidy tetraploidy

Explanation / Answer

Answer:

18. (E). a,b, and c all are correct

19.(a)

In paracrine signalling a cell produces a signal to induce changes in nearby cells,

20. (b) metabolism

It refers to all chemical reactions involved in maintaining the living state of the cells and the organism.

21. (d) citric acid cycle

The citric acid cycle produces two molecules of ATP for every molecule of glucose and eight molecules of NADH (equivalent to 24 ATP) and two molecules of FADH2 (=4 ATP) per molecule of glucose.
