Answer:
glutamine synthetase-glutamate synthase
b)Glutamate dehydrogenase catalyzes the same reaction, but only under conditions of very high NH4+ levels such as agricultural fertilizers since the reaction is unfavorable under standard conditions (ΔGº’ = +30kJ/mol). Under physiological conditions, this reaction deaminates glutamate.
Explanation:
The importance of the first reaction you can see that it needs a molecule of ATP in order to create the catalysm, so that´s why that enzyme is called synthetase, since it needs a molecule of ATP to do its work, the other one, the glutamate synthetase, because it does not need the molecule of ATP to do so.
Glutamate can only catalyze the reaction under certain not found in nature regularly conditions, that´s why it doesn´t work as a dehydrogenase.
Answer:
The correct answer is c. A:C
Explanation:
Thymine and guanine are most stable in their keto form and adenine and cytosine are most stable in their amino form. Sometimes these bases undergo tautomeric shift(proton shift) which converts them into rare less stable form called tautomeric form which are imino and enol form.
In this rare form, these bases can pair with the base which are not complementary to them. Like adenine base pairs with cytosine and guanine base pairs with thymine when present in rare form.
When these tautomeric forms of nucleotides incorporated in DNA they may cause mutation in the DNA.
Therefore the correct answer is c. A:C

Answer:
From your list of answers it would be to collect rock samples from the moon.
Explanation:
Answer:
The given steps are of light phase of photsynthesis.
1)A photon of light excites photosystem II.
2)A water molecule is split, the electrons are transferred to photosystem II.
3)Oxygen is formed as an endproduct.
4)An electron is transferred from photosystem II to the primary electron acceptor.
5)ATP is synthesized as the electrons pass through an electron transport chain to photosystem I.
6)A photon of light strikes photosystem I, an excited electron is transferred to the primary electron acceptor.
7) An electron is transfered from an electron transport chain from photosystem II to photosystem I's primary electron acceptor.
8)Electrons are passed from photosystem I through an electron transport chain.
9)NADP+ is reduced to NADPH.
