Answer:
The correct answer is - 130 kDa, 82 kDa, 45 KDa.
Explanation:
In the question given is there are 4 subunits in protein omicron in which two subunits are - 65 kDa and the other two subunits are - 85 kDa and 45 kDa.
So the size band would be in absence of beta-mercaptoethanol which is very essential to break down disulfide bonds that held together these subunits:
Size band = 65 KDa + 65 KDa
= 130 KDa (one band) (
65+65=130),
82, 45 as without beta mercaptoethanol disulfide bond is not broken
.
Thus, the correct answer is - 130 kDa, 82 kDa, 45 KDa.
Answer:Enzymes that makes redox reactions possible in a biochemical process includes those that help to catalyze the transfer of electrons, atoms, or functional groups.
Explanation:
Here are some class categories of these enzymes and their roles ;
• Oxidoreductases - Transfer of electrons (hydride ions or H atoms)
• Transferases - Group- transfer reactions
• Hydrolases - Hydrolysis reactions (transfer of functional groups to water)
• Lyases - Addition of groups to double bonds, or formation of double bonds by removal of groups Transfer of groups within molecules to yield isomeric forms
• Isomerases - Formation of C-C, C-S, C--0, and C-N bonds by condensation reactions coupled to ATP cleavage
The above are however classified, given code numbers, and assigned names according to the type of transfer reaction, the group donor, and the group acceptor.
Answer;
Medulla.
When you run to catch a ball, your movements are planned and controlled from the Medulla.
Explanation;
The Medulla directly controls certain autonomic (involuntary) responses, such as heart rate, breathing, blood vessel dilation, swallowing, sneezing and vomiting.
It is located in the brain stem, anterior to the cerebellum.
