Hydrogen bonds is holding together the two strands of nucleic
<span>Covalent bonds hold the atoms and molecules together in each of the amino acid chains. Two complimentary chains are held together by hydrogen bonds to form a double-helix.</span>
Answer:
The correct answer is serous glands.
Explanation:
The serous glands comprise serous acini, an array of serous cells, which discharge serous fluid isotonic with the plasma of the blood that constitutes enzymes like alpha-amylase. They are most predominant in the lacrimal and the parotid gland, however, are also found in the submandibular gland, and to some extent in the sublingual gland.
Answer:
The correct answer would be "net formation by fibrin threads"
.
Hemophilia is an X-linked recessive disorder in which a person is not able to produce clotting factors VIII (hemophilia A) or IX (hemophilia B).
These clotting factors are involved in the cascade of coagulation process which takes place after the formation of a platelet plug.
These clotting factors help in the conversion of fibrinogen (soluble protein) into insoluble fibrin which stabilizes the platelet plug and ensures that the wall of the vessel can be healed properly.
Answer:
All of these are correct.
Explanation:
ATP synthase is an F type pump with two multiprotein complexes. One of the protein complexes has three types of integral membrane proteins a, b and c while another protein complex has five polypeptides with distinct composition. It has three copies of each alpha and beta subunits and one copy of each gamma, delta and epsilon subunits.
The beta subunits have a binding site for ADP and Pi and catalyze ATP synthesis. Rotation of gamma subunits relative to the fixed alpha and beta subunits causes the catalytic binding site of each beta subunit to obtain either of three conformational states.
An O state has a high low affinity for ATP, ADP, and Pi while L state has a high affinity for ADP and Pi. The T state binds to ADP and Pi tightly to facilitate the formation of ATP. The T state also has a high affinity for ATP.
