the primary production. Darkness has no effect on respiration. This is because cellular respiration is actually the reverse process of photosynthesis. Oxygen is a necessity of life requirements for basically all living organisms.* In this lab we are testing how different levels of salinity in the water indirectly affects the gross primary productivity in aquatic plants. To measure this you would use the light and dark bottle method. Only respiration (R) can occur in the bottle stored in the dark.

Effect of Boiling on the Rate of Aerobic Respiration of Germinating Peas Abstract Aerobic respiration is an enzyme mediated process during which glucose is used to make ATP to fuel the cells energy needs. Germination is one of such processes that make use of aerobic respiration and because certain factors can affect aerobic respiration‚ it would also affect germination. In this experiment‚ we examined the effects of boiling on the rate of aerobic respiration of germinating peas. Unboiled germinating

The Effect of Varying Temperatures to the Rate of Respiration of Bufo marinus Statement of the problem: At which environmental temperature‚ do toads have the highest respiration rate? Most animals obtain oxygen‚ which comprise 21% of the air‚ from the environment. Oxygen combines with hemoglobin of the blood to form oxyhemoglobin. Oxyhemoglobin is transported to the tissues where oxygen is released and used for the metabolic functions of the animal. The functions produce waste materials‚ such

9/19/2012 Experiment #1-Density Aim: Learn how the process of distillation occurs. Observe how distillation separates alcohol from wine. Method: Distillation is based on the fact that the matter can exist in three phases - - solid‚ liquid and gas. As the temperature of a pure substance is increased‚ it passes through these phases‚ making a transition at a specific temperature from solid to liquid (melting point--mp) and then at a higher temperature from liquid to gas (boiling point--bp). Distillation

Fermentation Lab Introduction For bacteria and many single-celled protists fermentation is a common anaerobic pathway that the cells use to collect energy from carbohydrates to form ATP. The process for fermentation begins in the cytoplasm with a process called glycolysis‚ which converts one molecule of glucose into two molecules of pyruvate. When glycolysis is complete four ATP would be produced but the net yield would be two ATP taking into account the initial investment of two ATP

Meal Worm Cellular Respiration Experiment Introduction Cellular respiration provides energy to all living organisms by collecting energy from food molecules. The cell then rearranges complex molecules to simpler molecules and uses that energy to make a molecule that stores energy called adenosine triphosphate also known as ATP. Cellular respiration can occur with or without oxygen. When it occurs without oxygen‚ it is called anaerobic respiration. There are very few organisms that can get

whether living organisms by respiration convert oxygen into Co2. Introduction: The process by which organisms release energy from food is called respiration. There are two categories of respiration‚ depending on the amount of oxygen available. Aerobic respiration is the most common type of respiration. It requires oxygen- the reason why you are breathing right now. Anaerobic respiration requires no oxygen. The experiment which will take place is the aerobic respiration. Earthworms will be examined

Abstract Enzymes are affected by changes in pH. The most favorable pH value— the point where the enzyme is most active—is known as the optimum pH. This experiment was conducted to determine the effect of pH reaction rate on an enzyme‚ catalase‚ from yeast. The experimental results indicate that the catalase worked best at a neutral pH level of seven (7). Introduction An enzyme is a protein molecule that serves as a catalyst. “The basic function of an enzyme is to increase the rate of a reaction;

kinds of microscopes include; phase-contrast‚ dark-field‚ polarizing and UV. Each of these microscopes differs in the source and manner in which the light is passed through the specimen to be viewed. The microscopes that are usually used in biology labs are compound binocular or monocular light microscopes. Compound microscopes have a minimum of two magnifying lenses (ocular and objective). Binocular microscopes have two eyepieces while the monocular ones have one eyepiece. The ocular lens of a
