Metabolic Rate of a Mouse Lab Write-Up A . The purpose of this experiment was to measure the oxygen consumption of a mouse in which I concluded that they would have less consumption considering their much smaller size. It turned out that they produced 60 O /min which means they use about 0.0024 cal/min or 3.5 cal/day. That is indeed less than the amount we humans use‚ but if the given the mass of a human‚ they would use 15‚ 313 cal/day which is more than the 2‚000 calories we use on an

An experiment to investigate the effect of temperature on the rate of reaction of the Enzyme Trypsin. Aim: This investigation was on the effect temperature has on the rate that the enzyme trypsin hydrolyses its substrate‚ a protein found in milk (casein). This investigation was conducted under controlled conditions‚ the temperature being the changeable variable. Trypsin and its substrate (powdered milk which is a source of the protein casein) were heated in a water bath. The contents of the two

GREAT METABOLIC CHALLENGE Metabolism is a series of vital biochemical processes that take place in order to sustain life. During a marathon run‚ the individual relies on the breakdown of carbohydrates and lipids‚ in order to provide energy release in the form of Adenosine Triphosphate (ATP). This essay will focus on the role of mobilization and structures of both carbohydrates and lipids in the production of ATP. Mobilization of Carbohydrates When carbohydrates are consumed during a meal‚ catabolism

Energy and Enzymes. What is cellular work? Why must living things utilize energy with maximum efficiency? Define energy. Why do living things need a constant input of energy? Where does all energy in the biosphere originate? Define kinetic and potential energy. (Give biological examples). What are the two laws of thermodynamics? Give examples. What is entropy and what is the law of entropy? How do living things resist the law of entropy? Give biological examples. Define metabolism‚ catabolism and anabolism

Metabolic Superstorm 1. Fill in the chart below. Use “+” if the patient’s vital sign is higher than normal‚ “−” if the sign is lower than normal‚ or “x” if the sign is normal. If you need to‚ use your text or another resource to determine normal values. Vital Sign Increase/Decrease/Normal Respiration Rate + Heart Rate + Blood Pressure - Body Temperature + 2. If you were the doctors on the scene‚ what diagnosis would you give this patient? (You may

TITLE: Effect of the caffeine on the heart rate OBJECTIVE: To investigate the effect of the caffeine on the heart rate of living organisms. INTRODUCTION: * Daphnia Daphnia are small‚ planktonic crustaceans‚ between 0.2 and 5 mm in length. Daphnia are members of the order Cladocera‚ and are one of the several small aquatic crustaceans commonly called water fleas because of their saltatory swimming style (although fleas are insects and thus only very distantly related). They

The study of metabolism reaches as far back as the thirteenth century. With it‚ things like the citric acid cycle‚ mitochondrial physiology‚ and diseases like diabetes have been better understood. The overall concept of metabolism is key in any biological field and it helps ensure the survival of an organism. It does so by converting things like food that we ingest into energy via a series of somewhat complex biochemical reactions. This energy can then be used for a multitude of things including

cellular respiration is an example of chemical reactions. Throughout the chapter‚ the cell’s metabolism will be examined to understand how it controls the chemical reactions that take place in the cell. Section 6.1 - An Organism’s Metabolism Affects Energy and Matter The metabolism in cells is responsible for the series of chemical activities that take place in the cell. Metabolic Pathways The metabolism controls the material and energy resources of the cell. Through the

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
