What is the independent variable in cellular respiration?
Independent variables: temperature of water bath (Room or 10° C)
How do you measure the rate of cellular respiration?
Measuring Respiration Scientists can measure the rate of cellular respiration using a respirometer by assessing the rate of exchange of oxygen. Understanding the Ideal Gas Law is of fundamental importance for knowing how the respirometer functions.
What are the reactants of cellular respiration?
Carbon dioxide + Water Glucose (sugar) + Oxygen CO2 + H2O C6H12O6 + 6O2 Cellular respiration or aerobic respiration is a series of chemical reactions which begin with the reactants of sugar in the presence of oxygen to produce carbon dioxide and water as waste products.
What is the hypothesis of cellular respiration?
HYPOTHESES: The experimental hypothesis is that germinating seeds will show a greater rate of respiration than control glass beads. Additionally, that at higher temperatures, the rate of cellular respiration in the seeds will increase.
What is the independent and dependent variables in cellular respiration lab?
The independent variable is the type of peas (Germinated or Nongerminated) and the temperature (Room or Cold Temperature). The dependent variable is the consumption of oxygen from all 6 respirometers. The control group is respirometer three from both temperatures that consists of only glass beads.
What is the dependent variable for the cellular respiration experiment?
The dependent variable is the value that was measured or calculated during the experiment. In this case the dependent variable was either CO2 volume (ml) or the calculated respiration rate (ml CO2/min).
When ATP levels are high acetyl COA is channeled into?

What’s the average respiratory rate?
Normal respiration rates for an adult person at rest range from 12 to 16 breaths per minute.
What are the reactants for cellular respiration quizlet?
Cellular Respiration reactants are glucose and oxygen. Products for cellular respiration are H2O, ATP, and CO2.
What is the purpose of the cellular respiration lab?
When carbon dioxide reacts with water, a weak acid (carbonic acid) is formed (see chemical reaction below). The more carbon dioxide you breathe into the BTB solution, the faster it will change color to yellow. The purpose of this lab activity is to analyze the effect of exercise on cellular respiration.
What organelle do you need to do cellular respiration?
Mitochondria have an important role in cellular respiration through the production of ATP, using chemical energy found in glucose and other nutrients.
