My results went well compared to my prediction… Exercise 1: Cell Transport Mechanisms and Permeability: Activity 5: Simulating Active Transport Lab Report Pre-lab Quiz Results You scored 100% by answering 4 out of 4 questions correctly. In order to get 5. Was the pH level always within. Na+ and K+ both have a 3.
From there a longer time to achieve maximum tension increases. Rename this document to include your first and last name prior to submitting, e. According do E-R diagram Figure 7-20 the degree shows many to many which indicates there are several projects with several employees working on them. When the radius of the afferent arteriole was decreased, the pressure and the filtration rate both decreased. Why does it make sense to sell high-priced and exclusive merchandise such as diamonds, rare Cognac, or Waterford Crystal, through warehouse club channels? During a single twitch of a skeletal muscle You correctly answered: b. Fewer action potentials are recorded at R2 when lidocaine is applied because lidocaine blocks the voltage-gated Na+ channels between R1 and R2, which blocks the propagation of the action potential from R1 to R2.
If an animal has been thyroidectomized, what hormone s would be missing from its blood? When we breathe, we inhale oxygen and exhale carbon dioxide. The secretion of erythropoetin from the kidneys stimulates testosterone in males. Does diffusion allow osmotic pressure to be generated? Which of the following has the most negative voltage? If the membrane is composed of lipid portion. Describe the change you see in the trace. The data support the concept that the reduction of. Submit this completed document by the assignment due date found in the Syllabus.
Action potential, Antibody, B cell 1227 Words 6 Pages Name: Luis A. Terms in Review, 1-4, p 204 1. Thyrotropin-releasing The normal rat is You correctly answered: c. Skeletal muscle twitch- one contractile response to a single action potential. In diffusion, molecules move You correctly answered: a. Adrenal cortex, Endocrine gland, Endocrine system 714 Words 5 Pages Describe how negative feedback systems regulate body temperature. By adding more extracellular K+ the intracellular K+ will decrease and cause the membrane potential to become less negative.
What happens to the amount of total force that the muscle generates during the stimulated twitch? How does it compare to your baseline data, and why? How is this change in whole-muscle force achieved in vivo eg. Increase or decrease the stimulus voltage and repeat the experiment. Which of the following statements about metabolism is false? Both of the pressures in the beakers were not equal. Which of the following lists the anatomical structures in the correct order as they are encountered by the blood and filtered fluid during the process of filtration. Minute respiratory volume: 7,500 ml 2.
The extracellular Na+ did not alter the membrane potential in the resting neuron because the Na+ channels were mostly closed. Fewer intracellular K+ ions would result in the membrane potential being less negative. Key Terms: found in bold in Lab Manual Please define all bold terms in your own words: Enzymes- Large protein molecules made by your body cells. Primary sources — Actual records of artifacts, like letter, photographic, videos, memoirs, books, or personal papers that were created. The upper value indicates the. The response at R2 after lidocaine application will necessarily be zero because lidocaine blocks the propagation of the action potential from R1 to R2. Stimulus Frequency is the rate of delivered stimulus to the muscle.
Increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels because the membrane is permeable to K+ ions. Describe two Variables that affect the rate of diffusion. What is the pressure in the left lung? This is because the customer can still cancel and get a refund. Define the terms skeletal muscle fiber, motor unit, skeletal muscle twitch, electrical stimulus, and latent period. Version 42-0023-01-01 Purpose What is the purpose of this exercise? The exchange of oxygen and carbon dioxide between the lungs and blood is termed pulmonary diffusion and is. Yes pH levels in the blood did change, they increased over the course of the run 6. The higher concentration gradient would result in a reduced diffusions of K+ ions out of the neuron via the leak channels.
Read the Introduction and Objectives to understand the concept. Negative What does it mean that the voltage just inside the membrane is negative? Find the appropriate images to use as references and use your mouse to roll over the images and click on the highlighted structures. The risk-free interest rate is 8% per annum. Action potential, Axon, Electrophysiology 1246 Words 4 Pages Miguel Rodriguez Unit 6, Exercise 1 1. How well did the results compare with your prediction? Gas pressure inside the lungs is lowered.
High intensity activities lasting for less than 10 seconds. Did the pH level of the blood change at all during normal breathing? Negative What does it mean that the voltage just inside the membrane is negative? And 6 elements explain how the body responds to his physical activities particularly in relation to the musculoskeletal system, cardiovascular system and respiratory system. Which of the following processes does not occur during inspiration? The nature of plasma membrane. Minute respiratory volume: 7,500 ml 2. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels.
Watch… 1761 Words 8 Pages I have only listed the questions that required answers that are a part of this exercise. Therefore, the K+ ions will diffuse down its concentration gradient from a region of higher concentration to a region of lower concentration. Both the endocrine and nervous systems are major regulating systems of the body; however, the nervous system has been compared to an airmail delivery system and the endocrine system to the pony express. Exercise 1: Muscle Twitch Data Table 1A: Muscle Twitch of Rectus Data Table 1B: Muscle Twitch of Lateralis Eye Muscle Quadriceps Femoris Time milliseconds Tension kilogram-force. For at least three of these reasons, explain why this happens, if there is one or more type of implementation likely to minimize the occurrence, and if there is one or more type of installation more likely to induce failure for this reason.
