Which kind of muscle fibers enable the muscles to exert force for a long period of time? fast twitch slow twitch

Answers

The correct answer is slow twitch.  

There are generally two types of skeletal muscle fibers present in the body of humans. These are slow twitch fibers and the fast twitch fibers. The slow twitch fibers in the muscle allow the long endurance responses to the muscles, on the other hand, the fast twitch fibers generate a fast response in the muscles.


The question says, which kind of muscle fiber enable the muscle to exert force for a long period of time. The correct option is 'slow switch'. The slow switch muscle enable one to participate in long endurance feats such as long distance running. These muscles are red in colour because of the high quantity of myoglobin found in them.

Acetylcholinesterase is an enzyme that catalyzes the breakdown of the neurotransmitter acetylcholine. Which of the following explains why acetylcholinesterase cannot be used to catalyze the breakdown of other neurotransmitters, like norepinephrine?It would require a level of activation energy too high for acetylcholinesterase to react with other neurotransmitters.
      Binding with an alternate neurotransmitter would inhibit the reaction of the enzyme with acetylcholine.
      Reacting with another neurotransmitter would halt the production of the enzyme and raise the overall activation energy.
      Its shape determines the neurotransmitters that can reach its active center where activation energy is lowered.

I think it might be the last one

Answers

"Its shape determines the neurotransmitters that can reach its active center where activation energy is lowered" definitely best explains why acetylcholinesterase cannot be used to catalyze the breakdown of other neurotransmitters, like norepinephrine. You were right. Good job. :)

In functional genomics, biologists use sequence information to identify the functions of various parts of genomes. Which of the following kinds of information could not be obtained from a genome sequence?A: regulatory sequences such as gene promoters
B: rRNA genes
C: amino acid sequences of proteins
D: noncoding repetitive repeats and intron regions
E: specific proteins that are made by a cell under particular conditions

Answers

Answer:

E: specific proteins that are made by a cell under particular conditions

Explanation:

It is only specific proteins that are made by a cell under particular conditions can't be obtained from a genome sequence. In order to get information about this protein we need proteomics.

Genome sequence gives us an idea of nucleotide sequence of DNA and RNA molecules not proteins. Regulatory sequences such as promoters, enhancers, insulators, UTRs etc. all are a part of genome, rRNA genes are part of genome sequence too, non coding repetitive repeats and intron regions are also a part of genome sequence itself so option A, B & D are incorrect. Option C is also incorrect because amino acid sequence of  proteins can also be determined by genome sequences because each nucleotide triplet which is known as codon refers to a specific amino acid. Option E is correct because by genome sequence we can easily get to know about amino acid sequence but not about specific protein which is synthesized at a particular condition.
