Cellular respiration is the process of converting chemical energy of organic molecules such as glucose into a form of energy usable by organisms. This energy is mainly produced in the mitochondrial matrix and takes form in the molecule adenosine triphosphate [also known as ATP]‚ which is made up of an adenosine with a three phosphate tail group. The reason why ATP produces energy is due to the loss of the third phosphate group. The third phosphate‚ when released‚ releases the bond energy and supplies

MOTOR TEMPERATURE RATINGS A frequently misunderstood subject related to electric motors is insulation class and temperature ratings. This paper tries to describe‚ in basic terms‚ the temperature relationships that are meaningful in standard AC induction motors. Some of the same information can be applied to DC motors but DC motors are more specialized and some of the ratings are slightly different. Perhaps the best way to start is to define the commonly used terms. MOTOR SURFACE TEMPERATURES

Title: Amount of Oxygen‚ Mung Beans (Vigna Radiata) Consume during Cellular Respiration Introduction: Cellular respiration is a catabolic reaction that refers to the process of converting chemical energy of organic molecules into a simplify form so it can be used immediately by organism. Glucose may be oxidized completely if sufficient oxygen is available‚ by the following equation: C6H12O6 + 36 ADP + 36Pi + 6O2(g) 6 H2O + 6 CO2(g) + 38 ATP + heat All organisms‚ including plants and animals

There are many similarities and differences between the processes of aerobic respiration and photosynthesis. To start‚ aerobic respiration can be defined as a biochemical pathway through which chemical bond energy is released from food and changed into ATP. On the other hand‚ photosynthesis is manufacturing of carbohydrates out of CO2 and the splitting of water in the presence of light. Photosynthesis and aer. respiration can be the same in many ways. For instance‚ both of them contain cycles. In

TOPIC 3.7 + 8.1: CELL RESPIRATION 3.7.1 Define cell respiration. Cell respiration is the controlled release of energy from organic compounds in cells to form ATP (adenosine triphosphates). 3.7.2 State that‚ in cell respiration‚ glucose in the cytoplasm is broken down by glycolysis into pyruvate‚ with a small yield of ATP. Glycolysis in cytoplasm: Glucose 2 pyruvates + small amount of ATP (does not use oxygen) 3.7.3 Explain that‚ during anaerobic cell respiration‚ pyruvate can be converted

- Cellular Respiration Assignment - 1. What two molecules are formed when a phosphate is removed from ATP? There are three phosphate groups in ATP molecule (Adenosine Triphosphate)‚ when removing one phosphate molecule‚ ADP molecule is formed (Adenosine Diphosphate). 2. What is the function of ATP? Describe the molecule. The function of ATP is storing energy within a cell. ATP is adenosine triphosphate‚ C10H16N5O13P3‚ a high energy complex‚ giving the necessary power to push metabolistic

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

Abstract The experiment aims to observe if simpler substrates makes the rate of cellular respiration faster. Using yeast‚ smith fermentation tubes and different substrates namely‚ starch‚ lactose‚ sucrose‚ glucose and fructose‚ which are from different kinds of carbohydrates‚ ranging from the simplest sugars glucose and fructose to the polysaccharide starch and water as the control‚ the hypothesis was tested. With the span of thirty minutes with five-minute intervals‚ the height of carbon dioxide
