Sea Otter Metabolics and Thermoregulation Sea Otters (Enhydra lutris) have always intrigued me because they are one of the most recent additions to the marine environment having only been fully aquatic for about 1-3 million years‚ but what really peaked my interest was the fact that they maintain homeostasis as far north as Alaska without blubber in 13-17 degree water‚ and that the metabolic rate that they would have to have must be enormous so I decided to look into what it takes to keep an

A cycle is a biological pathway or process in which the end product of one cycle becomes the starting point for the next cycles Write an essay about cycles. Respiration Cells in the body use ATP as a direct source of energy. The conversion of glucose into ATP takes place during respiration. There are 2 different types of respiration‚ the more common and frequent one is aerobic respiration which is the production of ATP for energy. The less common one is anaerobic respiration‚ the production

Yogurt Fermentation Yogurt is made by lactic acid fermentation. The main (starter) cultures in yogurt are Lactobacillus bulgaricus and Streptococcus thermophilus. The function of the starter cultures is to ferment lactose (milk sugar) to produce lactic acid. The increase in lactic acid decreases pH and causes the milk to clot‚ or form the soft gel that is characteristic of yogurt. The fermentation of lactose also produces the flavor compounds that are characteristic of yogurt. Lactobacillus

In Class Assignment 6: Cellular Respiration Figure 1: Glycolysis 1) Glucose is considered what type of energy? 2) What energy molecule must be used to start glycolysis? 3) Based on your answer to question 1 why do you think ATP must be used to start glycolysis? 4) How many net ATP are produced by glycolysis? 2 5) What is the end product of glycolysis? Figure 2: The Krebs Cycle 6) How many pyruvates did one molecule of glucose produce? 7) Based on your

Glycolysis Regulation Task 3 (D4) Glycolysis is the breakdown of glucose into a compound called pyruvate. A net of two ATPs are produced as the process uses two ATPs and produces four. Glycolysis consists of ten chemical reactions; each reaction is catalysed using a different enzyme. Oxygen is not required during glycolysis so it is considered anaerobic respiration. Glycolysis must be regulated so that energy is produce only when required. During glycolysis there are three enzymes that catalyse

Seven Mystery Deaths Omesh Khemai Biology 1 Professor Depass 10.28.14 Case Study The first was a 12-year-old girl. Her parents said that she was awake in the middle of the night complaining of a stuffy nose and sore throat. They gave her an extra strength Tylenol and sent her back to bed. At 7am the next morning‚ the parents discovered that the girl had collapsed on the bathroom floor. An ambulance rushed the girl to a nearby hospital‚ where she was pronounced dead. That same day

HPE102A – Energy Systems The Sport I will be doing this assignment on is Basketball. The two drills activities I will explain are dribbling‚ and defending. The Lactic Acid System is the energy system being developed in drill 1. The energy system being used in drill 2 is the Aerobic System. Section 1 There are three energy systems used when playing sport; ATP-CP‚ Lactic Acid and Aerobic. The ATP-CP System lasts 15 – 30 secs and it doesn’t require oxygen. The Lactic Acid System lasts for 30 sec
