Cellular respiration involves a series of enzyme-catalysed reactions. The 3-carbon sugar is now built up to a 6-carbon sugar which can be converted into starch for storage. All organisms depend ultimately upon green plants as a source of organic nutrients.
Photosynthesis is one of the most fundamental biological reactions.
In order to satisfy their needs people destroy vast territories of forests, which are the source of oxygen. Initially, the oxygen in the atmosphere of the ancient Earth was very small. Appearance of chloroplasts and mitochondrion was a huge step in evolution that led to the appearance of first eukaryotic organisms 2 billion years ago.
A well-composed short or 5-paragraph essay should be informative, interesting, possess logical structure and persuade the reader in the importance of your thoughts, because an essay is not a strict research of the topic but the presentation of your personal opinion about it, your reflections based on the investigation on the topic.
Not all the 3-carbon sugar PGAL is converted into 6-carbon sugar.
Oxygen is required for this energy-releasing process to occur. These reactions are called carbon fixation reactions. Which process took longer?
Cellular respiration is the metabolic process in which food is broken down to form stored energy in the form of ATP. Why is the Elodea rinsed in distilledwater? Cellular respiration involves a series of enzyme-catalysed reactions. Photosynthesis uses water and carbon dioxide as reactants to produce glucose and oxygen where as cellular respiration uses glucose and molecular oxygen as reactants to produce water, carbon dioxide, and energy ATP.
Their oxidation in electron transport chain provides synthesis of 6 molecules of ATP. The starch is not the only end-product of photosynthesis. Niel suggested that water is the hydrogen donor in the oxidation-reduction that occurs in photosynthesis.
In order to live normally people require pure water and food. Now not all the electrons are returned via the electron carrier system to chlorophyll. The end product of photosynthesis is glucose, which is used further for synthesis of other important organic compounds.
Chloroplast ribosomes are smaller than cytoplasmic ribosomes.Possible Photosynthesis & Respiration Essay Questions CollegeNow Biology Exam 1. Aerobic multi-cellular organisms need oxygen in order to live. Cellular Photosynthesis and Respiration Essay Sample Photosythesis and Cellular Respiration are both processes in Biology which transform energy in one form to another.
Photosythesis is the process in which light energy is converted into chemical energy to produce glucose.
Photosynthesis and Cellular Respiration Essay Sample. Introduction This is an investigation of the effect of the intensity of light (photosynthesis) have on the rate of cellular respiration (measured as the number of oxygen bubbles).
Photosynthesis and respiration are reactions that complement each other in the environment. They are in reality the same reactions but occurring in reverse.
While in photosynthesis carbon dioxide and water yield glucose and oxygen, through the respiration process glucose and oxygen yield carbon. Photosynthesis is the process by which plants, some bacteria, and some protistans use the energy from sunlight to produce sugar, which cellular respiration converts into ATP, the “fuel” used by all living things.
Comparison between photosynthesis and respiration Photosynthesis and respiration are both processes that are necessary for the survival of organisms. However, in many ways these two processes are very different as they are responsible for contrasting necessities.Download
