Aim: This is an investigation to establish the effect of different temperatures (from 0°C -100°C) on the production of oxygen gas in a potato catalase reaction, using hydrogen peroxide as a substrate. The oxygen gas produced will be measured using a gas pressure sensor. Introduction: Enzymes are proteins, known as biological catalysts that increase the rate of reaction in a biochemical reaction without being chemically altered.…
My hypothesis that the germinated peas would consume more oxygen than the non-germinating peas was accepted. Looking at the results the germinated pea results of how much oxygen was consumed was much higher than the ungerminated peas. The hypothesis that the P. savitum would rise in oxygen consumptions as its temperature rose was accepted as well. Looking at the data and the line graph, it is clear that as each temperature got higher the amount of oxygen consumed went up as well. Most enzyme activity after 45ºC generally become denatured and can’t function properly.…
Determining the impact of Auxin in pea plants, and its effect on lateral bud growth Megan Posey Bio 121-104 John Barry 10/23/16 Abstract Auxin is a hormone that helps to regulate bud growth, cell elongation, and many other aspects of plants. Apical dominance is a phenomenon that occurs due to the presence of auxin and stops lateral bud growth.…
The procedure for Lab 5 contained four parts. For Part A, a clean, dry 100 mL beaker was obtained and filled with 60 mL of distilled water. Next, the beaker was placed on a ring stand with a thermometer attached to the ring stand to record the temperature of the water. After the thermometer had been in the water for two minutes, the temperature was recorded. Following the recording of the temperature, a 10 mL pipet and a bulb was used to pipet 10.00 mL of distilled water into a clean, dry, pre-weighted 50 mL beaker.…
Module 2 Assignment – SBI4U-TK Purpose: To observe the power of aerobic exercise compared to the power of anaerobic exercise, and how much glucose does exercise consume. Predictions: (a) Predict hoe many times more powerful aerobic exercise is than anaerobic exercise? = Triple (b) Predict how many teaspoons of table sugar you will “burn” after exercising your arm to exhaustion.…
26. In point form list four ways in which photosynthesis and cellular respiration and interdependent. Include the specific stages and molecules for both processes in your answers. 1. The glucose formed during the Calvin cycle in photosynthesis by some G3P molecules breaking off is used to release ATP during cellular respiration.…
At first, 30 germinated peas that had the same size were selected. The seed coat was removed from the seeds of the peas. The peas were put in a cup and the weight was measured. A water bath was used to put water and ice cubes to have a temperature of 10° C that was measured with a thermometer. The peas were soaked in the water for five minutes with a test tube that was inserted through a hole that the water bath contained.…
My group was assigned with seeds that have been germinated for 72 hours. The purpose of this experiment was to study cellular respiration in germinating peas at room temperature versus non-germinating peas at room temperature, versus germinating peas cold, by measuring and comparing their consumption of O2 and CO2. We compared the cellular respiration rate of germinating and non-germinating peas. Additionally, we observed how temperature affects cellular respiration by manipulating the temperatures of the water bath, and comparing the cellular respiration rate between the germinated peas at room temperature and the germinated peas in the cold water…
The data supported the hypothesis due to the fact that the rate of respiration was lower when the peas were put under colder temperatures of water. The respiration rate also increased when the temperature of the peas was higher when they were put under warmer temperatures of water. Throughout cellular respiration, the works of different enzymes were the ones in charged for these changes. Enzymes have a special way on how they work, when enzymes have a temperature that is higher than normal, the reaction will increase and they will work faster, but when the temperature of the enzyme is slower than normal, they will stop working as fast as they normally do. Something important is that they work really fast when they are putted under high temperatures,…
This time, I conducted both my quantitative and qualitative observations on group. The group consisted of an adult and a juvenile…
Introduction Photosynthesis is the process in which light energy is converted into chemical energy in plants and other organisms (Reece, 2011). Photosynthesis is a redox reaction where carbon dioxide is reduced to sugar (glucose) and water is oxidized to oxygen (Reece, 2011). The reaction that occurs during photosynthesis is shown through the empirical equation CO2 + H2O → (CH2O)N + O2 (Stegenga, 2015). Photosynthesis occurs in the chloroplasts of plant cells, specifically within the thylakoid and the stroma (Stegenga, 2015).…
I. Introduction Catalysts are stimulus that speed up the rate of a reaction by lowering the activation energy of the reaction. Chemists discovered catalysts when they were trying to determine how to turn one substance into another. Although early chemists did not resolve how to turn substances into one another, they did discover that various materials could be changed from one form to another. This also led to the discovery that if certain chemicals were present in the reaction, the change would occur faster without consuming itself in the reaction.…
Discussion The purpose of our experiment was to compare the rate of photosynthesis and respiration of Brassica rapa in ambient carbon dioxide concentrations, but grown in variable CO2 concentrations. The results we concurred from this experiment were the same as we had hypothesized, the variable growth conditions of the B. rapa plants had no significant difference on the rates of respiration and…
INTRODUCTION Cellular respiration is the breaking down of organic molecules by means of catabolic pathways that uses electron transport chain to produce ATP (Campbell 2011). ATP is used as energy in the synthesis of light or also known as Photosynthesis . ATP is used by photosynthetic organisms to produce their own food and also by performing cellular respiration. It needs mainly glucose and oxygen that involves the transfer of electrons in a chemical reaction.…
