1. In the following reaction‚ which of the following is an example of a substrate? Lactase Lactose → Glucose + Galactose a. Lactose 2. During photosynthesis‚ plants use light energy to synthesize glucose from carbon dioxide. However‚ plants do not use up energy during photosynthesis; they merely convert it from light energy to chemical energy. This is an illustration of: a. The first law of thermodynamics 3. Which would be an example of catalyst in action? a. A protein converting glucose

All of the microtubes contain ingredients that act as indicator for their reactions except for the TDA‚ IND and VP tubes which do not have indicator within the substrates. Most of the tubes will react by changing the colour due to pH changes and certain tubes changes colour with the help of the reagent in order to detect the metabolic product and reactions such as fermentation or oxidation for example for the tube containing inositol‚ sorbitol and rhamnose (SOR‚ INO‚ RHA) that changed to yellow colour

Lesson 5/ Key Questions: 18. In the morning‚ when you wake up‚ before you eat‚ go for a walk ‚ swim‚ something for around 3-10 minutes. It will help get your metabolism started and work better through out the day. I would suggest cutting those 2 beers a night into one‚ or maybe 2 every other day‚ or 2 a week. I would eat something like oatmeal in the morning‚ or simple toast with eggs and HAM. Bacon is high in fat and calories. And always get fruit. And Change up your lunch. Make a sandwich. or

This assignment will describe the role of energy in the body and explain the physiology of two named body system in relation to energy metabolism. It will explain where energy comes from‚ how the body uses energy‚ what is metabolism/catabolism and anabolism and also it will explain cellular respiration aerobic/anaerobic is. Energy is necessary for muscular activity and movement however‚ energy is also necessary to circulate blood and lymph and tissue fluid throughout the body; for breathing and

Section 9-1 Review Key Ideas 1. Identify the primary source of energy that flows through most living systems The sunlight. Autotrophs use sunlight to make their own food. Organisms that can’t make their own food consumed the food molecules made by autotrophs‚ eat autotrophs or eat organisms that consumed autotrophs. 2. Explain how an organism’s metabolism is related to Earth’s carbon cycle. An organism’s metabolism is related to using energy to build organic molecules which contain

Steps to Study Aerobic Cellular Respiration The mitochondrion made ATP How does the mitochondrion make ATP? Glycolysis breaks down a glucose molecule Pyruvate is created via Glycolysis The acetyl CoA is produced from Pyruvate Citric acid comes from acetyl CoA and Oxaloacetate Citric acid was the starting molecule for the Krebs cycle The NADH and the FADH2 were generated by the Krebs cycle Oxidative Phosphorylation involves electron transport chain (ETC) and Chemiosmosis

Aging‚ “The accumulation of diverse deleterious changes occurring in cells and tissues with advancing age that are responsible for the increased risk of disease and death.” (Tosato‚ 401). This major aspect of our life is still a mystery to scientists‚ however there are many theories behind the process‚ and reason humans and all living organisms age. Many studies have been performed to understand more about this phenomenon‚ yet no definitive theory has been stated. Free radical theory has been a popular

The Role of the Citric Acid Cycle The Citric Acid Cycle is a series of enzyme-catalysed reactions that take place in the mitochondrial matrix of all aerobic organisms. It involves the oxidation of the acetyl group of acetyl CoA to two molecules of carbon dioxide. Each cycle produces one molecule of ATP by substrate-level phosphorylation‚ and reduces three molecules of NAD and one molecule of FAD for use in Oxidative Phosphorylation. The cycle is preceded by Glycolysis‚ which also occurs in anaerobic

The carbon cycle is a biogeochemical cycle that displays how carbon circulates throughout the environment. Many components affect this process such as photosynthesis and cellular respiration. Photosynthesis uses the carbon dioxide that is in the atmosphere to transform it into sugar and oxygen; cellular respiration puts carbon dioxide in the air. Both of these processes were studied during the experiment. In the experiment‚ the tube with both the elodea and the snail had the same level of carbon

Cell wall composition • :Gram negative . • Gram positive. b. Nutritional requirements : • Autotroghs:take nutrition from carbon dioxide. • Heterotrophs take the nutrition from organic carbon(carbs‚lipids‚protein) • Prototroph: take nutrition from sunlight. • Chemotrophic take nutrition from chemicals. c. Oxygen requirement
