franciscana are known to live in high salinity lakes that are often basic (Biology 108 Lab Manual 2015). Furthermore‚ A. franciscana feed on photosynthetic phytoplankton which inhabit areas of light availability but are also more susceptible to predation in highly-lit areas (Biology 108 Lab Manual 2015). Also‚ A. franciscana can withstand a broad range of temperature except extreme values may affect survival (Biology 108 Lab Manual 2015). In this experiment‚ the habitat

This report will overview the redox reaction - cellular respiration: C5H12O6 + 02 → 6CO2 + 6H2O + Energy and it’s use with the human body. Cellular respiration is a chemical process providing the body with usable and fast source of energy in the form of ATP. Along with ATP cellular respiration also produces CO2‚ H2O and Heat. This is an organic redox reaction. Redox reactions Redox reaction occur when there is a movement of electrons between atoms. Part of a redox reaction include: Oxidising Agent:

Lab: Cellular Respiration in Yeast Lab Report Form Your Name: Katlin Moore “What do you think? – What do you know?” Questions: In this lab‚ we will investigate the effect of sucrose concentration on the rate of cellular respiration in yeast. Under specific conditions‚ yeast will convert sucrose into glucose and then use this glucose in cellular respiration. Yeasts have been used by humans in the development of civilization for millennia. What is yeast? How have humans used yeasts?

Investigation 5: Photosynthesis Problem: If the leaf disks are treated in a way you know increases the net rate of photosynthesis‚ should they start to float faster or slower? Why? Hypothesis: If the leaf disks were bathed in a red light source‚ then the rate of photosynthesis would increase than leaf disks that are bathed in a regular light source because chlorophyll absorbs red pigment and reflects green pigments. Therefore‚ shining a red light source onto the leaf disks would cause them

larCellular respiration in sports Kerb cycle The Krebs cycle refers to a complex series of chemical reactions that produce carbon dioxide and Adenosine triphosphate (ATP)‚ a compound rich in energy. The cycle occurs by essentially linking two carbon coenzyme with carbon compounds; the created compound then goes through a series of changes that produce energy. This cycle occurs in all cells that utilize oxygen as part of their respiration process; this includes those cells of creatures from the

The effect of different coloured lights on the rate of Photosynthesis Objective: To find out which colour of light provides the best consequences for the production of oxygen/ the rate of photosynthesis Background: In photosynthesis‚ there are two main parts‚ including light dependent and light-independent reactions. Plants use the energy from light for producing sugar‚ which is being converted into ATP by cellular respiration. They also are the only organisms that produce oxygen along with glucose

Title: Rate of Photosynthesis Introduction: Photosynthesis occurs in plants where the light energy changes to chemical energy. This process occurs in the chloroplast of the plant cell in order to have gas exchange in the organism. Purpose: To measure the effect of light intensity on the rate of photosynthesis in the leaf cells. Hypothesis: The higher the concentration of the sodium bicarbonate solution‚ the faster the leaf of the plant will rise to the surface of the water in the beaker‚ the
