Photosynthesis Background Do you know what is the most important process that sustains life? Photosynthesis‚ that is the correct answer! Photosynthesis‚ is known as the process to produce plant food. But‚ how does is the life exist on the planet we call our home‚ Earth? Photosynthesis is a process that we know that allows water‚ carbon dioxide‚ and some mineral salts along with the light from the sun to make glucose (sugar). During the process‚ the root sytem of the plant takes in elements

Evidence of Photosynthesis Photosynthesis is the process during which a plant’s chlorophyll traps light energy and sugars (glucose) are produced. In plants‚ photosynthesis occurs only in cells with chloroplasts. Water (H2O)‚ carbon dioxide (CO2) and light energy are required. The light energy is absorbed by the green pigment‚ chlorophyll‚ and is converted into chemical energy‚ which causes the water drawn from the soil to split into molecules of hydrogen and oxygen. The hydrogen combines with

Benjamin Tiger1/16/12 Cellular Respiration Questions 1. Aerobic pathways require oxygen‚ while anaerobic pathways don’t. Anaerobic pathways only require the process of glycolysis to produce energy. Anaerobic pathways are found outside the mitochondria within the cytoplasm of the cell‚ with a low efficiency of 4%. These pathways require glucose‚ ATP‚ adolase‚ fructokinase‚ dehydrogenase‚ and NAD+. Out of one glucose molecule‚ major products include two net ATP‚ two NADH‚ and two pyruvate

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:

were performed involving photosynthesis and cellular respiration. The first part of the lab consisted of cutting out spinach leaf disks with a straw and then putting them into syringes containing an infiltration solution and sodium bicarbonate. Then the syringes were place under the presence of light and watched as certain disks floated. This part of the lab consisted of watching photosynthesis take place. Then for the second part of the lab we tested cellular respiration by putting the syringes in

Factors Limiting Photosynthesis The rate of photosynthesis increases with increasing light intensity. But too much light intensity can slow down the rate of photosynthesis because the light damages chloroplasts in the leaf. The higher the temperature the greater the rate of photosynthesis as photosynthesis is a chemical reaction and chemical reactions increase with temperature. But at temperatures above 40 C the rate slows down because the enzymes involved are destroyed

between light intensity and photosynthesis that could normally be seen had the experiment taken place without errors. The graph should show an increase in arbitrary units the further away from the light source the beaker is because the greater the distance from the light source‚ the lower the light intensity and so less photosynthesis would take place in the algal balls. This would result in more CO2 being present because it wouldn’t be being used up during photosynthesis. The decrease in CO2 in the

Lab Report: Photosynthesis Name: Purpose of this Lab What is the goal of this lab? What question are you trying to answer‚ or what problem are you trying to explain? In this lab I will perform experiments to explain photosynthesis. I will answer questions like what does photosynthesis do and how does photosynthesis work? Hypothesis After reading the lab instructions (but before starting the lab) record your best educated guess about what will happen in the experiment. Explain

References | PAGE | 1.0 Introduction Respiration usually occurs in two ways‚ aerobically and anaerobically. Aerobic respiration uses oxygen to function and anaerobic respiration functions without oxygen. Generally‚ anaerobic respiration starts by breaking down the molecules of glucose and produces pyruvic acid. The pyruvic acid then undergoes fermentation to produce ATP‚ the basic energy source in our human body. Although this kind of respiration is less efficient in producing energy‚ because

wavelength of light on the rate of photosynthesis was investigated in this experiment. The results from Figure 13 suggest that white light‚ containing all wavelengths of coloured light‚ has the highest rate of photosynthesis. Purple light had the second highest efficiency‚ followed by blue‚ red‚ and yellow light. Green light was significantly less efficient‚ producing the second lowest pH reading (Figure 14). The samples exposed to no light had the lowest rate of photosynthesis. The hypothesis that white
