    Ribosomes are the proteins with rRNA that contain enzymes responsible for forming peptide bonds between the amino acids, while tRNA is the adaptermolecules which bring the proper amino acid to the ribosome which matches the codons on mRNA

  • What is the end product of aerobic glycolysis?
    What is the end product of aerobic glycolysis?
    The correct answer is option B Glycolysis is the process of breaking down glucose. The end product of glycolysis is Pyruvate. Pyruvate can be used for aerobic respiration in the TCA (citric) cycle if oxygen is present but if oxygen is absent, pyruvate is used in anaerobic respiration. The net end products of glycolysis are: 2 pyruvate, 2 ATP and 2 NADH. Lactic acid is the end product of anaerobic respiration. Pyruvate is converted to lactic acid; carbon dioxide and water are also formed in anaerobic respiration. Pyruvate is converted to acetyl CoA prior to entering the TCA cycle. Citrate is formed in the TCA cycle from acetyl CoA and pre-existing molecule of oxaloacetate.

  • What is P50 of sickle cell hemoglobin?
    What is P50 of sickle cell hemoglobin?
    1. 31-a p50 less than 26 mm hg defines a leftward shift of the oxyhemoglobin dissociation curve, which means that at any given pao2, hemoglobin has a higher affinity for o2. a p50 greater than 26 mm hg describes a rightward shift of the oxyhemoglobin dissociation curve, which means that at any given pao2, hemoglobin has a lower affinity for o2. conditions that cause a rightward shift of the oxyhemoglobin dissociation curve are metabolic and respiratory acidosis, hyperthermia, increased erythrocyte 2,3-dpg content, pregnancy, and abnormal hemoglobins, such as sickle cell hemoglobin or thalassemia. alkalosis, hypothermia, fetal hemoglobin, abnormal hemoglobin species, such as carboxyhemoglobin, methemoglobin, and sulfhemoglobin, and decreased erythrocyte 2,3-dpg content will cause a leftward shift of the oxyhemoglobin dissociation curve.

  • Are potassium's chemical and electrical driving forces similar or opposite?
    Are potassium's chemical and electrical driving forces similar or opposite?
    Potassium’s electrical and chemical driving processes are opposite to one another. The two forces exert a driving force that pushes sodium out of cells during difference in its concentration. While the electrical force causes the sodium to be pulled into the cells. The actual means of understanding the process is complex. Basically there is a chemical gradient that depends on the relative concentrations of two ions on each side of the membrane. While the electrical force exerts an influence depends on the charges on the two ions as well as the concentration difference and the charges which ultimately produces a balanced effect.

  • Which of the following sign is assessed by the nurse f Dennis has a lithium level of 2.4 mEq/L?A. WeaknessB. DiarrheaC. Blurred visionD. Fecal incontinence
    Which of the following sign is assessed by the nurse f Dennis has a lithium level of 2.4 mEq/L?A. WeaknessB. DiarrheaC. Blurred visionD. Fecal incontinence
    What the nurse should look for is letter C. When Dennis exhibits a sign of blurred vision, it may be accompanied by a lot of other symptoms. The nurse should also check if the patient is showing signs of vomiting and nausea. Take note that the if the lithium levels would further increase, this can lead to seizures and further complications. Take note that lithium is only supposed to be given at 0.6-1.2mm. Any amount that is beyond that will already be problematic to the individual. A lithium level of 2.5 mEq/L is already considered to be deadly some may die because of this. Chronic toxicity can be very problematic.

  • Which one of the following is not a characteristics of chemical synapses?
    Which one of the following is not a characteristics of chemical synapses?
    The correct answer to this question is C. At a chemical synapse, one neuron releases neurotransmitter molecules into a small space (the synaptic cleft) that is adjacent to another neuron. The neurotransmitters are kept within small sacs called synaptic vesicles, and are released into the synaptic cleft by exocytosis. These molecules then bind to neurotransmitter receptors on the postsynaptic cell's side of the synaptic cleft. Finally, the neurotransmitters must be cleared from the synapse through one of several potential mechanisms including enzymatic degradation or re-uptake by specific transporters either on the presynaptic cell or possibly by neuroglia to terminate the action of the transmitter.

    It took me a minute to understand this question because hypoventilation means that carbon dioxide levels are high. However, the question states that CO2 remains the same while oxygen increases. I had to realize that it was asking for the condition previous to the administration of treatment, not pertaining to the levels after treatment. Maybe specify this more? Thanks, great quiz
