Fischer Lab Time/Date: 7:00 PM/Wednesday Activity 1 Metabolism and Thyroid Hormone Part 1 1 Which rat had the fastest basal metabolic rate (BMR)? The normal rat had the faster basal metabolic rate‚ because it was not missing its pituitary gland or its thyroid gland. 2 Why did the metabolic rates differ between the normal rat and the surgically altered rats? How well did the results compare with your prediction

Exercise 2: Skeletal Muscle Physiology: Activity 3: The Effect of Stimulus Frequency on Skeletal Muscle Contraction Lab Report Pre-lab Quiz Results You scored 100% by answering 4 out of 4 questions correctly. 1. During a single twitch of a skeletal muscle You correctly answered: b. maximal force is never achieved. 2. When a skeletal muscle is repetitively stimulated‚ twitches can overlap each other and result in a stronger muscle contraction than a stand-alone twitch. This phenomenon is known as

potential. 3. 4. 5. K+ is more permeable than Na+ in a resting neuron. This is because there are few sodium leakage channels. 6. Since the resting membrane potential is the potential difference between the inside and outside of the cell across the membrane‚ a change would depend on the resting permeability of the membrane to ions. Activity #2 1. 2. Graded potentials can be said to be momentary‚ localized changes in the membrane potential that can be either depolarizing or hyperpolarizing. 3. In the

Mechanism 4 shows the debromination of 2α-bromocholestan-3-one to give 4. This mechanism which is similar to a Favoskii rearrangement‚ is likely to go via this path as other research has shown that there is often a by-product with this reaction. The by-product is cholest-4-en-3-one which requires the intermediate seen in the third molecule in the above mechanism. The intermediate is highly strained and with the presence of base a proton will be extracted which aids the collapse of the three membered
