Pages • 2
What happens to carbon atom during photosynthesis?(Light dependent reactions) ·Light depended reactions occur inside the thylakoids. When the chlorophyll molecules absorb sunlight they give off high energy electrons. They move through a series of electron carrier proteins called electron transport chains in the thylakoid membrane. The proteins in the electron transport chain use the energy to pump hydrogen ions into the thylakoid from the surrounding stroma. The stroma is the gel like fluid inside the chloroplast. The hydrogen ions pumped…...

Aerobic respiration is the process for transforming Glucose into Co2(Carbon dioxide). and H20(Water as waist product) with the participation of oxygen (O2) for produces energy. As a function, aerobic respiration provides fuel for the repair, growth, and maintenance of cells and tissues. It is the process by which many cells, produce energy using nutrients and oxygen. It also gives rise to carbon dioxide, which later must then release. (equation a mettre). This equation explains why both nutrients and oxygen are…...

The purpose of this investigation is to compare the ability of two different strains of yeast to respire, when using different sugars as respiration substrates. Considering the lengths that have been reached to develop varieties of yeast with greater suitability and effectiveness for very particular fermentation purposes, it seems reasonable to suppose that two different strains of the same species of yeast, selected for their different fermentation properties, have developed requirements that are not uniform. As a result of the…...

When looking at the graphs to show how the Shirley tomato plants grew, it is clear to see how each plant differed according to the feed used. Plants 1 and 2 were fed with Tomorite, plants 2 and 3 with Bio and plants 5 and 6 were controlled (only the nutrients found in the soil). From the ratios, we can see that Bio has three times the amount of nitrogen as Tomorite. In addition, Tomorite has double the amounts of…...

The Effect of Temperature on the Anaerobic Respiration of Yeast
Words • 3527
Pages • 13
Aim: To investigate the effect of temperature on the rate of respiration in a suspension of yeast Saccharomyces cerevisiae. Background Knowledge: Yeasts are a form of eukaryotic microorganisms classified in the kingdom Fungi, with approximately 1,500 species known. They reproduce asexually by budding mainly, although some species reproduce by binary fission. They are unicellular, although some species with yeast forms may become multicellular due to way in which they normally reproduce. Typically the size of a yeast cell is approximately…...

Enzymes are the tools of life. They do almost everything in a cell. Virtually every one of life's chemical reactions is driven by some enzyme. Enzymes are organic catalysts that work like a starter on a car. With a small input of energy from the starter, a car can run on its own energy all day. They don't get not used up or changed when they "jumpstart" another molecule. They can perform the same task over and over working very…...

An insight into aerobic type training(blood lactate) for athletes.Type II muscle fibers oxidize lactate at a very fast rates. When muscle contraction produces a significant amount of lactate, it is then released into the central circulation of the blood, and within seconds it is made available to that muscle for energy. Therefore, 75% of the lactate produced from high intensity exercise is made available for energy production in type II muscle fibers. The remaining 25% of lactic acid is used…...

The carbon-oxygen cycles are actually two independent cycles. However, both these cycles are interconnected as well as interdependent on each other to some extent. There are four processes involved in the completion of the carbon-oxygen cycle. Oxygen-carbon cycle processes are: * Photosynthesis Plants undergo photosynthesis that helps them produce energy and food for themselves. During photosynthesis, plants take in carbon dioxide (CO2) and absorb water (H2O) with the help of their roots. The chlorophyll present in the leaves and the…...

Cellular respiration is a metabolic process where the body uses organic molecules to produce energy. One of the greatest energy sources that our body uses is glucose. In cellular respiration glucose is broken down, and the energy from those bonds is used to create adenosine triphosphate (ATP). There are two types of respiration: aerobic and anaerobic. In aerobic respiration there are 3 main steps: Glycolysis, Krebs Cycle (Citric Acid Cycle), and Oxidative Phosphorylation. In anaerobic respiration you can have alcohol…...

Photosynthesis and respiration are both processes that are necessary for the survival of organisms. However, in numerous ways these two processes are very diverse as they are responsible for distinct necessities. Therefore they both have similarities and differences. One major difference between the two is that photosynthesis takes place completely in plants while respiration occurs equally in plants and animals. Nevertheless to understand Photosynthesis and respiration, we need to understand what is photosynthesis and cellular respiration and examine each of…...
