More essays like this: My hypothesis was that if the lettuce was darker then it would show more cellular respiration than that of a lighter shaded plant.
After that we put the nonabsorbent cotton ball over the absorbent ones to protect the peas from the NOH. Ap bio essays cell respiration then added the 25 sprouted peas to two of the respirometers, the unsprouted and beads to another two and the glass beads to the last two.
Graph four represents the change in the amount of oxygen consumed by the different types of lettuce over time in the ice water. Glycolysis is a process that takes place in te cytosol and it oxidizes glucose into two pyruvate.
Room Temp Green Lettuce: This is because germinating peas need to consume more oxygen in order to continue to grow. The ATP synthase is located inside the chloroplast for photosynthesis.
Compare it to the effect of temperature on chemical reactions. First of all, cellular respiration is the metabolic processes whereby certain organisms obtain energy from organic molecules.
Then we put parafilm around the glass pipets and then put them snuggly into the rubber stoppers. Explain the effect of temperature on the overall volume of gas inside the respirometer.
This graph represents the change in oxygen consumed by the different types of lettuce over time in the room temperature water. In procedure one, the purpose was to determine the affect the temperature has on both sprouted and nonsprouted peas.
Ice Water 0 minutes Equilibrium.
In the first lab, our respirometer for the glass bead in the cold water leaked, ruining our control. Anther type of protein is the carrier protein. PP S to S Questions 1. However, the variables on the side of the graph are quantitative because they are all numbers.
We then put one absorbent cotton ball in each respirometer. Graph 3 shows the amount of oxygen that was consumed for each lettuce in just the regular water. Then record how far the dye has moved after every 5 minutes. My hypothesis is that if the peas are geminated then they will show a higher amount of cellular respiration in comparison to nongerminated peas.
Graph two shows the change in oxygen consumed by the peas over time in the ice water. Ice Water Glass Beads: In the second lab my group completely forgot a control so we were only able to compare the results in the same tub. Discussion The first lab did support my first hypothesis.
So there was one iceberg respirometer, one green lettuce respirometer and one red-leaf lettuce respirometer in each tub. This process includes glycolysis, the Krebs cycle, and the Electron Transport Chain. After that we put the nonabsorbent cotton ball over the absorbent ones to protect the lettuce from the NOH.
After that put a piece of paper under each of them and then added a drop of food coloring to each of the respirometer glass pipets and completely submerged the respirometers in the water. In the inner membrane of the mitochondrion, there is an electron transport chain.
Next time we need to be more accurate with our work, speed up our pace, and plan things more thoroughly ahead of time. Both of these graphs have quantitative variables on both axes because they are all numbers.
The membrane structure plays an important role in the transportation of materials across the membrane. These labs did not go nearly as well as planned. Then we used water displacement and made the volume of each of the different pieces of lettuce the same. This caused us to only get about 10 minutes of data.Start studying AP Biology: Cell Respiration.

Learn more about cellular respiration, fermentation, and other processes that extract energy from fuel molecules like glucose. AP Bio: Lab 6 Cellular Respiration Essay Sample Introduction Some knowledge that is needed before performing this lab are as follows: First of all, cellular respiration is the metabolic processes whereby certain organisms obtain energy from organic molecules.
Adenosine triphosphate (ATP) is the main product of cellular respiration, and the molecular energy of the cell. Aerobic metabolism results in a much higher yield of these energy carrying molecules due to the fact that it can use oxygen as a final electron acceptor in the electron transport chain.
AP Bio Photosynthesis & Respiration ____In a plant cell, where are the ATP synthase complexes located? a. thylakoid membrane b. plasma membrane Respiration is the reversal of the biochemical pathways of photosynthesis. b. Photosynthesis stores energy in complex organic molecules, while respiration releases it.

The cell membrane is made up of phospholipids that have hydrophobic tails and hydrophilic heads. The proteins have hydrophobic and hydrophilic regions that determine if they get embedded.Download
