Which symptom is unique to amyotrophic lateral sclerosis (als) and is not observed in multiple sclerosis (ms)?

Nonamiya [84]

ALS is a rapidly progressive and fatal neuromuscular disease. MS is a scarring and hardening of the sheath around the nerves in the brain, spinal cord, and optic nerve. MD is a muscular disorder with specific kinds of MD involving different muscles in the body. MD is almost exclusively hereditary

<h3>What is Amyotrophic lateral sclerosis (als) ?</h3>

The motor neurons steadily degrade and eventually die as a result of ALS. The brain, spinal cord, and all the muscles in the body are connected by motor neurons. When motor neurons are destroyed, they stop communicating with the muscles, which prevents the muscles from working.

Five to ten percent of all ALS cases are familial, meaning the patient gets the illness from a parent. Typically, only one parent needs to have the disease-causing gene to have familial ALS.

Pyruvate dehydrogenase is regulated by feedback inhibition and covalent modification. Which molecules inhibit the pyruvate dehyd

Oksi-84 [34.3K]

ADP, NAD+, CoA-SH, and pyruvate are the molecules that inhibit the pyruvate dehydrogenase complex.

<h3>What is pyruvate dehydrogenase complex?</h3>

PDC3 triggers the oxidative decarboxylation of pyruvate, resulting in the creation of acetyl-CoA, CO2, and NADH.

The PDC plays a crucial role in the oxidation of glucose by connecting the glycolytic pathway to the tricarboxylic acid cycle's oxidative pathway.

ADP, NAD+, CoA-SH, and pyruvate all inhibit it. PDK prevents glycolysis from being coupled to GO by inhibiting its target enzyme PDH.

Thus, the answer is ADP, NAD+, CoA-SH, and pyruvate .

PLEASE OH GOD HELP ME PLS I LOVE U.

Nostrana [21]

Remember that a controlled variable is a variable that stays the same thoughout the experiment.

it wouldn't be a. because two different wires were used

the final length of the wax would be your dependent variable, so it wouldn't be c.

the thermal conductivity is the independent variable so it isn't d.

the original length of the wax was the same for both.

So B is your answer.

Louisa notices that she has been gaining weight although she has not changed her diet. Louisa's doctor suspects she might have a

vladimir2022 [97]

The most appropriate technique that the physician should use to estimate the basal metabolic rate of Louisa's body is indirect calorimetry.

<h3>What is indirect calorimetry?</h3>

Indirect calorimetry is a medical technique for determining a person's resting energy expenditure. This technique is used to calculate the calories your body expends in a resting situation.

Information obtained from indirect calorimetry can be used as a guide to basal metabolism to determine whether it is normal, increased, or decreased.

Based on the above, this is the best technique the doctor has to find out why Louisa is gaining weight without changing her diet.
