What formula could we use to calculate the rate of respiration in this experiment.
Select all that apply:
Change in O_2O2 / Change in Time
Change in Time / Change in O_2O2
Change in CO_2CO2 / Change in Time
Change in Time / Change in O_2O2
It is essential for the cells in plants and animals to have an adequate supply of oxygen. Explain what the oxygen is needed for in the cells? (Be as specific as possible.)
A student doing the cellular respiration lab forgot to add KOH to their respirometer.
When it is time to detect cellular respiration, describe in detail how this mistake experimentally would change their results.

- If a mouse and a small lizard of the same mass were placed in an experimental chamber under identical environmental conditions, which animal would consume oxygen at a higher rate? Explain.arrow_forwardI'm studing Cellular Respiration. We did a lab. We had technical difficulties... our CO2 gas sensor wasn't working properly. So I am curious, what trends SHOULD I have seen. We compared the CO2 output of bean sprouts vs mealworms. We tested at both room temp (27 degrees C) vs cold temp (15 degrees C) for both the mealworms and bean sprouts. I need to know the trends I should have seen, ie. does an animal or plant produces more C02 and why? Also does the the cool temp make the reduction in CO2 production? Thank you.arrow_forwardUse the following data and the RER table from your lab for the next couple of questions. Jane is 5'5" and 63 kg, and she generates the numbers in the table below on the respirometry cart. What would Jane's RQ, or RER be? VO2 (LO2/min) CO2 (LCO2/min) 0.20 0.14 0.19 0.13 0.23 0.16 0.21 0.15 0.19 0.12 0.22 0.15 0.21 0.16 0.18 0.12 0.20 0.14 0.20 0.14 What kind of fuel is Jane burning during the test?

You collect the data you see below in the table. Answer the following questions. Temperature Metabolic rate (ml oxygen/ml) 5°C (41°F) 258 25°C (77°F) 197 Identify the dependent and independent variables in this experiment. Dependent: _________________________________________________________ Independent: ________________________________________________________ List 2 other variables would need to be controlled in the experiment. 1. 2.arrow_forwardIn the Cellular Respiration Lab Why is it necessary to absorb the carbon dioxide (CO2) in the vials?

- 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: ______arrow_forwardSuppose that the germinating beans have been placed in boiling water for 5 minutes before placing them into the respirometer. Explain the effect of subjecting the mung beans in high temperature on the rate of respiration.arrow_forwardYou are studying with a friend who is describing the Bohr effect. She tells you that in the lungs, hemoglobin binds oxygen and releases hydrogen ion; as a result, the pH increases. She goes on to say that in actively metabolizing muscle tissue, hemoglobin releases oxygen and binds hydrogen ion and, as a result, the pH decreases. Do you agree with her reasoning? Why or why not?arrow_forward
- In a study of O2 uptake by muscle at high altitude, a physiologist prepares an atmosphere consisting of 79 mole % N2, 17 mole % 16O2, and 4.0 mole % 18O2. (The isotope 18O will be measured to determine O2 uptake.) The total pressure is 0.75 atm to simulate high altitude. Calculate the mole fraction and partial pressure of 18O2 in the mixture.arrow_forwardTemperature (°C) 10 30 50 60 70 Number of bubbles of gas produced per minute 0 3 7 12 7 4 1 Mr. Hughes prepares his wine by adding yeast to grape juice. The airlock (which allows gas to be released) at the top of the carboy (large glass container) detects bubbles of gas released by the yeast cells. Mr. Hughes notes that the rate of respiration varies with temperature, (which he can control using ice and heating belts) as indicated by the data above. 1. Sketch a graph of the data from this experiment. Be sure to properly label the independent and dependent variable. You should also have a proper title and appropriate scale, and neatly and properly graph the data for full marks. 40 20arrow_forwardMechanical ventilation is indicated when the patient's spontaneous ventilation is inadequate to sustain life by hooking the patient into a mechanical ventilator. It provides breathing support until lung function is restored, delivering warm (body temperature 37° C [98.6° F]), 100% humidified oxygen at FiO2 levels between 21% to 100%. 1. Discuss the process how does positive-pressure ventilator deliver air to the lungs? List 3 risks or complications of patient who is hooked in mechanical ventilator and discuss how it is even possible.arrow_forward
