respire anaerobically. It is proven once it smelled like alcohol. 2. Aerobic respiration occurs in the presence of oxygen‚ CO2 and water are produced‚ and occur in plant and animal cells. In Aerobic respiration‚ glucose is broken down into CO2‚ H20 and ATP; more ATP is released (38). Anaerobic respiration happens in the presence of no oxygen and occurs in many anaerobic bacteria and in muscle cells. During this respiration‚ either lactic acid or alcohol is produced. Glucose is broken down into Lactic

ABSTRACT The hypothesis which states that the simpler the nature of substrate‚ the faster the rate of cellular respiration of yeast was tested using the smith fermentation tube method. The experiment used six smith fermentation tubes‚ distilled water and sugar substrates. It composed of six set-ups which used 15ml of 10% yeast suspension‚ 15 ml distilled water and 15 ml of their assigned sugar substrate namely: starch‚ lactose‚ sucrose glucose and fructose respectively. Set-up six was the

complez or golgi apparatus packages proteins and lipids for transportation. Mitochondria in cells vary depending on the function of the cell. They can vary in numbers from hundreds to thousands. They are the source of energy for cells through aerobic respiration and manufacture ATP. The Liver and Kidneys are very active and their cells have large numbers of mitochondria. Ribosomes are located in varying parts of the cell‚ and can be bound or free floating. They are the garbage cans if the cells and their

Experiment on Cellular respiration of Mung Beans Seeds with the Effects of Temperature Introduction: ATP is generated from aerobic respiration from the use of biosynthetic pathways. Glycolysis is where respiration starts in the cells and produces ATP‚ NADH‚ and 2 pyruvate molecules from the oxidation of six carbon carbohydrate and glucose. Even if oxygen is there or not‚ enzymes are mediated in the cytoplasm. The electron transport chain‚ chemiosmosis‚ and aerobic respiration use NADH molecule

PLASTIDS Plastids are large cytoplasmic organelles. Plastids are major organelles found in the cells of plants and algae. Plastids are the site of manufacture and storage of important chemical compounds used by the cell. Plastids often contain pigments used in photosynthesis‚ and the types of pigments present can change or determine the cell’s colour. The term plastid was derived from the Greek word plastikas meaning formed or moulded. This term was coined by Schimper in 1885. In plants

As humans‚ we are the most dominant species in the world. We have the ability to walk upright‚ grasping thumbs‚ and large brains. This helps us to live and be successful on earth. But‚ these advantages we have didn’t happen overnight‚ they occurred during the hominine evolution. The skull‚ neck‚ spiral column‚ hip bones‚ and leg bones of the early hominine species changed shape in ways that later enabled species to walk upright. The evolution of dipedal‚ or two-footed‚ locomotion was very important

Transport Chain (ETC) are the three phases of cellular respiration used to completely catabolise glucose. a) Glycolysis occurs in the cytosol (or cytoplasm)‚ the Krebs cycle occurs within the Mitochondria (or mitochondrial matrix) and the Electron Transport Chain occurs on the Inner Mitochondrial Membrane (Cristae- fold). b) Anaerobic respiration occurs when low amounts of oxygen (02) are present‚ releasing low amounts of energy. Aerobic respiration requires the presence of oxygen and releases high

format of ATP’’ ATP (also known as adenosine tri-phosphate) is produced. Respiration is conducted from the cell membranes inside the mitochondria. Aerobic respiration provides a lot of energy needed per molecule of glucose (the level of ATP produced can be as high as 38 ATP molecules per 1 molecule of glucose. When the body is exercising intensely respiration happens faster and the muscles need more oxygen. Anerobic respiration uses a reaction of glucose and water to make energy it creates by-products
