1. Catabolism – Is the breakdown of organic substrates‚ Releases energy used to synthesize high-energy compounds (e.g.‚ ATP) ATP – • Oxidative Phosphorylation • Is the generation of ATP • Within mitochondria • In a reaction requiring coenzymes and oxygen • Produces more than 90% of ATP used by body • Results in 2 H2 + O2 → 2 H2O • Electron Transport System (ETS) • Is the key reaction in oxidative phosphorylation • Is in inner mitochondrial membrane • Electrons carry chemical energy

Cellular respiration is a series of metabolic processes by which living cells produce energy through the oxidation of organic substances. Photosynthesis is the process by which green plants and some other organisms use sunlight to make foods from carbon dioxide and water. A critical cycle of energy and matter that supports the continued existence of life on earth are formed by cellular respiration and photosynthesis. When it comes to the stages of cellular respiration‚ there are three stages. The

Enzymes are biologic polymers that catalyze the chemical reactions that make life as we know it possible. The presence and maintenance of a complete and balanced set of enzymes is essential for the breakdown of nutrients to supply energy and chemical building blocks; the assembly of those building blocks into proteins‚ DNA‚ membranes‚ cells‚ and tissues; and the harnessing of energy to power cell motility‚ neural function‚ and muscle contraction. With the exception of catalytic RNA molecules‚ or

REVIEW SHEET‚ EXAM 3 Chapter 6‚ Nutrition and Microbial Growth Define the four major modes of nutrition in microorganisms and distinguish among them in terms of energy and carbon sources The four major modes of nutrition are: 1. Photoautotrophs: (ex. Plants‚ some protozoa‚ & alegae) -microorganism which use carbon dioxide as a carbon source and light energy from the environment to make their own food. 2. Chemoautotrophs: -microorganism which uses carbon dioxide as a carbon source and

Enzymes are responsible for multiple reactions that take place naturally in the living organisms. The purpose of the enzymes lab was to investigate how the enzymes play a role in a reaction‚ affecting the rate of reaction (ROR). Interestingly‚ we tested how the enzymes affect the reaction rate at multiple temperatures (0‚ 23‚ 37‚ 50‚ 70‚ and 95 C). It was predicted that an increase in temperature will elevate the thermal activity of substrate which increases the chances the substrate molecules will

Abstract This experiment focuses on the effects water bath temperatures have on D. melanogaster entering and recovering an anoxic coma. It was found that there was an indirect relationship between the amount of time it took D. melanogaster to enter and recover from an anoxic coma and the temperature of the water bath. D. melanogaster was able to enter and recover from the anoxia coma quicker when they were drowned in a cold water bath condition when comparing these results to the warm water bath
