If it is something beneficial,how can its formation be promoted?
please do not copy from others
Step by step
Solved in 3 steps
- Crystal: Calcium oxalate or calcium phosphate in kidney stones If it is something harmful, what can be done to avoid its formation? please do not copy from othersBlood volume must be restored in a person who has lost large amounts of blood due to serious injury. This is often accomplished by infusing isotonic NaCl solution into the blood. Why is this more effective than infusing an isoosmotic solution of a penetrating solute, such as urea?Renal tubule cells in the kidney medulla are constantly exposed to high extracellular osmolirity. How do they maintain normal cell volume?
- Match the structures a mixed triglyceride a mineralocorticoid steroid hormone a weakly amphipathic molecule that modulates membrane fluidity prostanoic acid as the parent compoundIs phosphate H2PO4 non polar or polarGout is caused by an error in metabolism that leads to abuildup of uric acid in body fluids, which is deposited as slightlysoluble sodium urate (C₅H₃N₄O₃Na) in the joints. If the extra-cellular [Na⁺] is 0.15 Mand the solubility of sodium urate is0.085 g/100. mL, what is the minimum urate ion concentration(abbreviated [Ur⁻]) that will cause a deposit of sodium urate?
- Flippases help maintain membrane asymmetry. True FalseWhen a person becomes dehydrated the amount of water in extracellular fluids such as blood decreases, causing the solute concentration of these fluids to increase. State weather osmosis results in water entering or leaving cells.Which of the following causes the kidney to conserve/retain sodium? a. aldosterone b. vasopressin c. oxytocin d. corticosterone Which of the following class of chemicals exerts its effects by entering cells, binding intracellular receptors, and affecting gene expression? a. Peptides b. Steroids c. Bioactive amines d. Amino acids
- Hint: ( Ans) A plasma membrane pump Calmodulin is a protein whcalciumich plays an important role in performing variety of functions and which sense the presence of calcium.Intra cellular calcium levels are maintained by calmodulin path way.Renal tubule cells in the kidney medulla are constantly exposed to high extracellular osmolarity. How do they maintain normal cell volume?Severe vomiting and diarrhea cause a loss of water and solutes from extracellular fluids. If the person was given only water, what effect would this have on the solute concentration of the extracellular fluids? Would osmosis results in water entering or leaving cells?
