Extracellular calcium ions are important for the contraction of what type(s) of muscle tissue?

1 answer:

8 0

Extracellular calcium is important for the contraction of smooth muscle tissue as well as the cardiac muscle tissue. Both smooth muscles and cardiac muscles do not have the sarcoplasmic reticulum and t-tubule system found in skeletal muscles where calcium ions are stored for the initiation of excitation contraction coupling. In smooth muscles and cardiac muscles, calcium comes from the extracellular space which triggers the excitation contraction coupling.

What is the main function of the nucleolus? it produces enzymes that are then exported to the lysosomes. it produces cell adhesi

Kisachek [45]

The role of the nucleolus is to make the monomer of of ribosomes, and ribosomes are used in mRNA to make protein. Therefore the nucleolus plays a major role in the process of making proteins for our body.

Which of the following is not a part of the process of translation?a. initiator tRNA binding to the ribosome b. removal of intro

inna [77]

Answer: b. removal of introns from mRNA

The process by which Ribosomes attached to ER or lying freely in the Cytoplasm synthesize proteins from the transcribed mRNA of the DNA is called Translation.

Explanation:

It is made up of three stages;

1. INITIATION;Options C mRNA binding to the ribosome

2. ELONGATION ;Option D joining large and small ribosomal subunits

3, TERMINATION;Option E chain termination at a stop codon

However, Introns are non coding region of RNA base sequence transcribed from the DNA, or sections of DNA encoding the RNA. It is an unwanted part which must be sliced out before translation. Therefore it is not a relevant steps of translation, and hence Option B is the wrong answer.

Note the coded part of RNA trancripts is called EXONS. this the part with the needed information.

If the liver begins to release glycogen because the pancreas releases glucagon, the amount of ______ in the bloodstream must be

zheka24 [161]

If the liver begins to release glycogen because the pancreas releases glucagon, the amount of the concentration of insulin in the bloodstream must be too low.

Explanation:

Glucagon is considered to be the primary catabolic hormone of the body and is produced by the pancreas.

When insulin in the bloodstream falls low, then the pancreas causes the liver to convert stored glycogen into glucose. Insulin allows glucose to be used by insulin-dependent tissue.

The body releases insulin and glucagon to keep the blood glucose level stable in the body. Under stress, the level of glucagon increases in the body.
