Answer:
DNA is a double stranded molecule that belongs to a group of larger molecules (macromolecules) called NUCLEIC ACIDS.
Nucleic acids are formed by joining together many smaller molecules called NUCLEOTIDES.
Nucleotides consist of:
- Pentose sugar (pentagon)
- Phosphate group (circle)
- Nitrogenous (rectangle)
The answer would be Activational <span />
Answer:
c. There is more ATP in the system than ADP or AMP.
Explanation:
ATP is an energy molecule, and in the equation is the most important parameter. if you have all concentrations equal, the answer is EC=0.5 independently of the values
If you add more ADP on the system, the total will be reduced due the term on the numerator is divided by 0.5 - values are usually between 0.5-0.6
If you have more ATP on the system the numbers will automatically arise, due the importance of ATP term on the numerator, usually the EC is equal to 0.8-0.87.
If there is more AMP on the system numbers fall because the denominator is much greater than numerator. Usually the EC is equal to 0.5
Answer:
The correct answer is d the positive feed back reduces change in the the system
Explanation:
In an biochemical reaction when the released product stimulate the release and activation of the same product and act together to exibit their biological function, then this type of regulation is called positive feedback.
The positive feed back mechanism leads to increased change in the system that"s why it is named so.
For example during blood clotting platelets molecules are released to form clots to stop bleeding. one activated platelet can stimulates the activity of other platelets which then join together to form a group for generating further blood clots.
