Biology & Chemistry with Lab Week V INTRODUCTION In this lab Photosynthesis is a process used by plants and other organisms to convert energy from the light, the most common solar light into chemical energy that can be later released to fuel the organisms' activities. And this happen on plants. Photosynthesis can be represented using a chemical equation. The overall balanced equation is... 6CO2 + 6H2O ------> C6H12O6 + 6O2 Sunlight energy Where: CO2 = carbon dioxide H2O = water

Purpose The purpose of this lab was to investigate the relationship of light intensity and the rate of photosynthesis. Introduction This lab was conducted to examine the two biological processes of photosynthesis and cellular respiration. Photosynthesis is a process that uses carbon dioxide, water and energy to produce glucose and oxygen. Cellular Respiration is the reverse process of photosynthesis. Cellular Respiration uses the glucose and oxygen to produce carbon dioxide, water and energy.

Brandi Long Environmental Science-204 July 12, 2012 I-Lab#1 Deforestation Exercise 1 Discuss 5 products that come from tropical rain forests. A lot of the ingrediants that make of medication that is used in today’s world come from tropical rain forests, like Lapacho (Pav D’ arco). This is used for chemotherapy medicine for patients that have cancer. Lapacho has been noted to be beneficial for other conditions, like bacteria, viruses, parasites

NAME: Bobby Morris How do photosynthesis and cellular respiration compare? Follow the directions in the virtual lab to complete the photosynthesis and respiration puzzle. Make sure to read the virtual “book” (or use your textbook) to correctly order the processes. When complete check your results. Copy and paste your Screen Shot here. JOURNAL QUESTIONS 1. What is the importance of the light and dark reactions in photosynthesis? Light Dependent Reaction is the initial stage

consider is what the cause of global warming is, and the answer to this basic question is greenhouse gases. Greenhouse gases are natural gases such as CO2, Nitrous Oxide or Methane and are created in one of two ways. The first way is, through natural cycles, for instance, CO2 is released through animal respiration or plant photosynthesis. The alternative greenhouse gas production comes from man’s use of different fuels and products; this can lead to anthropogenic climate changes. Anthropogenic Climate

their maximum and minimum. This means that light intensity has the largest effect on photosynthesis rate on these days but it does not mean it is at the lowest and highest rates because there are many other factors involved such as temperature, and carbon dioxide

There are two types of cellular respiration, aerobic and anaerobic. Aerobic respiration is more efficient and can be used in the presence of oxygen. Aerobic respiration, or cell respiration using oxygen, uses the end product of glycolysis in the TCA cycle to produce more energy currency in the form of ATP than can be obtained from an anaerobic pathway. Fermentation (anaerobic respiration) (2 points) Fermentation is a metabolic process converting sugar to acids, gases or alcohol. It occurs in yeast and bacteria

The Role of Polysaccharides and Monosaccharides in Metabolism and Their Rate of Carbon Dioxide Produced During Fermentation Abstract Fermentation is the metabolization of sugars with carbon dioxide being produced as a result. Using yeast to ferment different types of sugars, we tested the rate of carbon dioxide production. Our findings of sucralose producing a slower rate of carbon dioxide than glucose during fermentation, are supported by the fact that polysaccharides are harder to break down than

1. Reflect on the autotrophs and heterotrophs in your Ecocolumn by answering the questions below: Two autotrophs that can be found in my Ecocolumn are the anacharis located in the aquatic environment and the pinto bean plants located in the terrestrial environment. Two heterotrophs found in my Ecocolumn are the ladybugs that live in the terrestrial region and the guppies which are in the aquatic region. Data that we recorded from our Ecocolumn demonstrated that both the autotrophs and the heterotrophs
