Consider modeling the concentration of a chemical in a lung using the table below. Fill in the missing values and calculate the concentration at time t = 1 if the starting concentration is   c0 = 0.11 mmol/L (millimoles per liter). Suppose the volume of the lung is V = 2.5 liters, the volume of air inhaled and exhaled in each breath is W =1.5 liters, and the ambient concentration of the surrounding air is a fixed 0.18 mmol/L. STEP Volume (L) Chemical (mmol) Concentration (mmol/L) Before Exhale 2.5   0.11 Exhale 1.5   0.11 After Exhale     0.11 Inhale 1.5     After Inhale       The concentration at time t = 1 is c1: ______

00 %24 w/ Charles' Law Change the simulation to "Charles' Law" by clicking the tab at the top of the screen it will be shown in white. You should see the picture below on your screen. 1. Which one of the three variables: Pressure, Volume or Temperature cannot be changed in Charles' Law? This varlable is considered a constant. 1. a. Using the Temperature controls, increase the temperature of the gas. What changes do you observe in the behavlor of the particles of the gas while the temperature is increased? b. Continue to increase the temperature value until T, = 44K. Using the equation for Charles' law, calculate the volume of the gas at this increased temperature. Check your final answer for part b by clicking the calculate button next to V2: c. Based on the final value calculated in part b) is Charles' law considered a direct or an indirect relationship between the variables? Explain your cholce with reasoning. 1. 2. Press the reset button at the top right of the screen. Using the…

Explain why the gas values from the alveolar air to the blood change during pulmonary gas exchange. For example: Alveolar air for CO2 has a value of 40mmHg then when entering the blood shifts to 45mmHg. Why does this occur? I tried to calculate this by using Dalton’s law but I’m not Understanding.

Below are multiple oxygen binding affinity curves for hemoglobin. The affinity curve for normal hemoglobin in blood is represented by curve "D," at a pH of 7.2 and at a concentration of 5mM BPG and 26 mM CO2. O₂ saturation (%) 100 Answer 1: B Answer 2: [Select] Answer 3: B Answer 4: 80 A 60 1. How would changes to acidity, BPG concentration and CO₂ levels affect the binding affinity curve and p50? lower than Answer 5: E 40 1. BPG concentration is decreased to 3mM: The binding affinity curve would look like B. The p50 would be lower than normal (D). 2. pH is increased to 7.6: The binding affinity curve would look like B. The p50 would be [Select] normal (D). 20 3. CO₂ concentration is increased to 30 mM: The binding affinity curve would look like. [Select] The p50 would be Answer 6: 0 normal (D). II. The hemoglobin has been treated with a denaturing solution which disrupts quaternary structure only, and has a binding affinity resembling myoglobin. The binding affinity curve would look…
