Two hypothesis. Germinating peas should consume more oxygen than non-germinating peas. Peas germinating at warm temperatures should consume more oxygen than peas germinating at cold temperatures 2.This activity uses a number of controls. What conditions must be kept constant?.

Cellular Respiration Lab Report Wednesday 8:00 A.M. Lab March 2nd‚ 2005 I. Introduction In this lab we are measuring the amount of oxygen used in both germinating and non germinating peas. We are measuring the oxygen consumption by taking a reading of a respirometer submerged in two water baths. The first bath will be cold water and the second warm to determine the effect of temperatures on oxygen consumption. Our negative control will be glass beads to measure to increase or decrease

December 8‚ 2011 AP Biology Lab 5: Cellular Respiration Introduction/Lab Objective: In this lab we are testing how the process of cellular respiration is affected by temperature‚ and also how it is different between germinating and non-germinating peas. Cellular respiration is a catabolic process (breaks down organic material into usable cell energy) that produces ATP. The electron receivers are inorganic. Cellular respiration releases energy from organic material through chemical oxidation within

of H2O produces 1 mol of CO2 through cellular respiration. Autotrophic organisms capture free energy from the environment through the process of photosynthesis and chemosynthesis. Hypothesis: The germinating beans will discharge more CO2 than the peas that are not germinating.

The cells can obtain their energy in different ways but the most efficient way of harvesting stored food in the cell is through

effect of temperature on the rate of CR in the germinating versus non-germinated seeds in a controlled experiment. Analysis: 1. The CR is higher in the germinating peas in the cold water rather than in the beads or non-germinating peas. The cold water probably slowed the process of CR in both germinating and non-germinating peas. 2. The conditions that must remain constant are: the water baths‚ the same amount of KOH‚ the same amount of time for equilibration‚ the same time measurements‚ and

gradients and 36 ATP from glucose (Campbell‚ 2008). In procedure one‚ the purpose was to determine the affect the temperature has on both sprouted and nonsprouted peas. My hypothesis is that if the peas are geminated then they will show a higher amount of cellular respiration in comparison to nongerminated peas. Also‚ if the different types of peas are placed in the colder water then they will show a slower rate of respiration than they will in room temperature water (Carolina Biological‚ 2006). In procedure

BIG IDEA 2 6 EDVO-Kit: AP06 Cellular Respiration See Page 3 for storage instructions. EXPERIMENT OBJECTIVE: The objective of this experiment is to apply the gas laws to the function of the respirometer. Students will observe cell respiration of germinating and non-germinating seeds and describe the effects of temperature on the rate of cell respiration.
