Physioex 9.1 exercise 2
PhysioEx 9.1 is a computer-based laboratory simulation program that allows students to perform virtual experiments and observe the effects of various physiological processes. Exercise 2 of PhysioEx 9.1 focuses on the effects of temperature on the rate of enzyme-catalyzed reactions.
Enzymes are proteins that catalyze chemical reactions in the body. They are essential for maintaining the many metabolic processes that keep the body functioning properly. Enzymes work by lowering the activation energy required for a reaction to occur, which makes it more likely that the reaction will take place.
In Exercise 2 of PhysioEx 9.1, students are asked to observe the effects of temperature on the rate of an enzyme-catalyzed reaction. The enzyme used in this exercise is peroxidase, which catalyzes the breakdown of hydrogen peroxide into water and oxygen.
To begin the experiment, students first need to set up the appropriate equipment and prepare the enzyme solution. They then need to measure the rate of the enzyme-catalyzed reaction at various temperatures by measuring the amount of oxygen produced over a specific time period.
As the temperature increases, the rate of the enzyme-catalyzed reaction also increases. This is due to the fact that increased temperature leads to an increase in the kinetic energy of the reactant molecules, which makes it more likely that they will collide with the enzyme and undergo the reaction. However, there is a point at which the rate of the reaction begins to decrease, even as the temperature continues to rise. This is because the increased temperature can also denature, or change the shape of, the enzyme, which can cause it to become less effective at catalyzing the reaction.
In conclusion, Exercise 2 of PhysioEx 9.1 demonstrates the effect of temperature on the rate of enzyme-catalyzed reactions. It is an important concept in the study of physiology, as it helps students to understand how the body's metabolic processes are affected by changes in temperature. Understanding these processes is essential for the diagnosis and treatment of various physiological conditions, as well as for the development of new drugs and therapies.
Skeletal Muscle Physiology 9.1
The length of the rest period will not substantially impact the length of time for sustained muscle tension. Lección 2 Estructura 2. You correctly answered: c. Your answer: The force is generated from stretching the muscle caused by the recoil of the tissue. Review Sheet Results 1.

¿Es de Miami Juan? You correctly answered: c. At the maximal voltage, all the muscle fibers contained in this muscle are depolarized and they all develop active force that is, they were all successfully recruited. You correctly answered: d. . Experiment Results Predict Question: Predict Question 1: As the stimulus frequency increases, what will happen to the muscle force generated with each successive stimulus? Define the terms skeletal muscle fiber, motor unit, skeletal muscle twitch, electrical stimulus, and latent period. You correctly answered: a. Your answer: Because as the weight of the load increases, the latent period time increases and the shortening velocity speed decreases.

You correctly answered: d. Muscle tension increases and decreases between different values for an unfused tetanus. When lifting a heavy load You correctly answered: d. Another way to increase the force produced by a muscle is to You correctly answered: d. In resting skeletal muscle, calcium is stored in You correctly answered: c.
Physioex 9.0/9.1 Exercise 2 activity 2 answers
If an intervening rest period is imposed on active skeletal muscle You correctly answered: c. You correctly answered: c. Explain how each is achieved in vivo. Your answer: When a skeletal muscle fatigues, contractile force decrease because force isn't generated any more after reaching maximal tetanic tension by previous contractile activity. Your answer: This muscle tension is called maximal tetanic tension. Yes, the second twitch generated more muscle force. Your answer: Maximal shortening velocity is only attained with a minimal load.
Stimulus frequency refers to the rate of stimulus. There will be a limit to this increase. With our help, your homework will never be the same! This phenomenon is known as You correctly answered: c. When the weight is heavy, the speed in which the muscle lifts the weight decreases in speed at a slower velocity. With a team of extremely dedicated and quality lecturers, physioex 9. If you were using your bicep muscles to curl a 7-kg dumbbell, when would your muscles be contracting isotonically? Why does this occur? You correctly answered: b. Will the muscle change length? Describe the process of excitation-contraction coupling in skeletal muscle fibers.

Note that a decrease in maximal force indicates muscle fatigue is developing. There will be a limit to this increase. Skeletal muscle fibers are innervated stimulated by You correctly answered: c. During an isotonic concentric contraction, the You correctly answered: b. You correctly answered: d.
Physioex 9.1 Exercise 2 Activity 2 Answers
How was each achieved in the experiment? Your answer: The shortening distance decreased with the heavier load. Describe the force of contraction with each subsequent stimulus. The number of motor fibers that available influence the motor recruitment. You correctly answered: b. Which of the following statements concerning this observation is true? If the muscle is shortened to its resting length, the active force increases. The electrical stimulus mimics acetylcholine release at a neuromuscular junction Review Sheet Results 1. Experiment Data: Voltage Length Active Force Passive Force Total Force Latent Period 0.

The Bohr radius of the H atom is 52. What happened in the isolated skeletal muscle when the maximal voltage was applied? Will there be a limit to this response? Review Sheet Results 1. All the steps of excitation-contraction coupling occur. Learn vocabulary, terms, and more with flashcards, games, and other study tools. During an isometric contraction You correctly answered: d. You correctly answered: d.
Is the total muscle force generated by the higher frequency stimulation greater than the force generated in previous stimulations? When the stimulus frequency reaches a value beyond which no further increase of skeletal muscle force can occur, the muscle has reached its You correctly answered: c. The muscle changing length would not be from the result of muscle contractions, but only from the weight pulling down. Intracellular concentrations of ADP and Pi declined during the rest period.
