1. The calcium ion concentration on a blood test reads 9.2 mg/deciliter. How many calcium ions...
(1) Mitochondria regulate the concentration of calcium ions in the cytoplasm, by allowing the ions to equilibrate across the mitochondrial membrane. If the mitochondrion has a membrane potential of –150 mV relative to the cytoplasm, and the cytoplasmic concentration of Ca2+ is 1 μM, what is the mitochondrial Ca2+ concentration? Assume a temperature of 37 C. (2) The membrane calcium pump of the malarial parasite Trypanosoma cruzipumps out calcium ions from the parasite cell interior, hydrolyzing one molecule of ATP...
2. Calcium levels in healthy adults are normally distributed with mean 9.5 mg/dl per deciliter and known standard devtion. A physician in a rural community suspects that the mean calcium levels are different for women i this comunity. He collects measurements from 20 healthy women and finds = 9.2 with sample standard deviation s 1.1. (a) (1 point) Describe the parameter of interest to the physician (b) (2 points) State the nl and alternative hypotheses (c)(1 point) Suppose we assume...

MOLARITY REVIEW 1.) How many nitrate ions are present in a 25.00mL sample of a 2.50M calcium nitrate solution? 2.) How many mL of a 0.300M lead(II) nitrate solution are needed to react with 50.00mL of a 0.500M potassium chromate solution? (solution stoichiometry problem) 3.) How many mL of a 0.700M Ca(NO3)2 solution are necessary to react with 25.00mL of a 1.000M H2SO4 solution? 4.) 25.66mL of a solution hydroxide solution reacts with 22.55mL of a 0.888M phosphoric acid solution,...
(6 points) Total cholesterol levels less than 2.00x 10 milligrams per deciliter (mg/dL) are considered desirable for adults. Use this border-line concentration to calculate how many grams of total cholesterol the individual's body may contain if the total blood volume of the individual is 5.4 L. 8.
