Assignment 1 UNIT 1 Question 1 (5 marks): Discuss the rate-limiting factor. Why is it important to consider when studying exercise physiology and training? Provide one example to clarify your understanding. The rate-limiting factor is the “step” that limits performances (the “slow step”). If we know the rate-limiting step in a certain physiological pathway or training situation‚ we can manipulate the factors of this step to change and increase the rate of the pathway. This will improve overall training

This lab focused on three factors affecting reaction rates‚ temperature‚ surface area‚ and concentration. Our first experiment (table 1) looked mainly into the effects of temperature on the reaction rate. To see how different temperatures would change the reaction rates we had three flasks all containing varying temperatures of water(H20). One with cold water (4°C)‚ one room temperature (21°C)‚ and one with hot water (44°C). In each flask‚ we dropped one tablet of Alka-Seltzer‚ all within 0.008 grams

The recent surge in oil prices is due to a large amount of consumption‚ especially in the U.S. in which 25 percent of the world ’s oil output is used. The increase in global oil consumption last year was the highest increase in nearly 30 years. A second reason for the rising oil price is that supplies are

Determination of rate of photosynthesis INTRODUCTION Photosynthesis is the major process by which light from the sun is captured by plants‚ algae and some bacteria to produce energy. It is a process in which light energy is converted into chemical energy which is then stored in sugars. Photosynthesis occurs in two stages‚ light-dependant reactions and light-independent reactions. In light-dependent reactions the chlorophyll traps light energy which is then used to excite electrons and split water

“Pulsation Rate of Blackworms” Antonio Cavazos Biology 1107- 102 (Tuesday 1:00 – 3:50) 04/ 07/ 2009 Jose Fierro Addison Rhudy I. Introduction For any animal that is too large and/or too complex a circulatory system is needed to obtain essential chemicals by the process of diffusion alone. A circulatory system transports nutrients‚ oxygen and other important chemicals to all body cells. This system have three components: circulating fluid‚ a heart or pulsating vessel in charge

Banking Concept: Simplifying RBI Key Policy Rates What are the key policy rates used by RBI to influence interest rates? The key policy or ’signalling’ rates include the bank rate‚ the repo rate‚ the reverse repo rate‚ the cash reserve ratio (CRR) and the statutory liquidity ratio (SLR). RBI increases its key policy rates when there is greater volume of money in the economy. In other words‚ when too much money is chasing the same or lesser quantity of goods and services. Conversely‚ when there

The Effect of Exercise on Heart Rate The aim of this investigation is to find out how different types of exercise can affect my heart rate. To measure and record my heart rate‚ I am going to undergo an experimental test. I am going to do 3 different types of exercise: walking‚ light jog and lastly hard running. First‚ I will draw out a table to record my results‚ and then I will measure my resting heart rate for one minute. To make the experiment as accurate as possible‚ I will

Assignment Topic 2 AUD/USD Exchange Rate The main movements of the AUD/USD exchange rate in the past eighteen months will be studied‚ as well as the underlying conditions that caused these specific movements to happen. Economic models and theories will be used to support the discussion and to analyse the reason for these fluctuations. Discussion will then take place to whether these movements have been a help or a hindrance to the overall health of the Australian economy. FIGURE 1.0

Changes in Equilibrium Interest Rates Shifts in Demand Shifts in Supply Example: Interest Rates and the Business Cycle By studying Mishkin’s Chapter 4‚ we learned how interest rates could be measured for a wide variety of credit market instruments. But what economic factors serve to determine these interest rates in the first place? To answer this question‚ we will

Lab#: 15 Title: Exercise/pulse rate Aim: To investigate the effect of exercise on the pulse rate Materials/ Apparatus: Stop watch Diagram: Procedure: 1. The three middle fingers were placed just behind the bottom of the wrist as indicated in the diagram in order to see if the pulse could be felt. 2. (a) If the pulse was not felt the three fingers were moved about until it could be felt. (b) Changing the hand also helped to find the pulse. 3. The number of pulsation
