<em>Answer: The human body uses amino acids to produce proteins, perform critical metabolic functions in the formation of other molecules and to produce energy. Some amino acids are synthesized by the human body, but the essential amino acids must be obtained from food.</em>

A researcher synthesizes a new molecule called inhibitor X that inhibits the activity of phosphofructokinase (PFK), the enzyme t

Oduvanchick [21]

Answer : The dissociation constant of the PFK‑inhibitor complex is, 5 µM

Explanation :

The expression for reversible competitive inhibition when apparent Km affected by addition of the inhibitor is:

$K_m_a=K_m[1+\frac{I}{K_i}]$

where,

$K_m_a$ = apparent value = 52 µM

$K_m$ = Michaelis–Menten constant = 40 µM

I = inhibitor concentration = 1.5 µM

$K_i$ = dissociation constant of the PFK‑inhibitor complex

Now put all the given values in the above formula, we get:

$52\mu M=40\mu M[1+\frac{1.5\mu M}{K_i}]$

$K_i=5\mu M$

Therefore, the dissociation constant of the PFK‑inhibitor complex is, 5 µM

According to the endosymbiotic theory, which cellular process was involved in the evolution of mitochondria and chloroplasts?

tatyana61 [14]

Answer:

This process would be the one truly responsible for the "evolution" of mitochondria and chloroplasts as we know them from their prokaryotic ancestors. The cell process that would have initiated endosymbiosis is endocytosis; the process of taking things inside the cell

The energy an organism requires to transport materials and eliminate wastes is obtained directly from

nirvana33 [79]

Answer:

ATP

Explanation:

ATP is regarded as 'root of energetics' for living organisms. So, the organisms utilizes ATP to transport material and eliminate wastes from the body. Not only these functions are carried out by ATP but also several others infact all energy requiring processes are carried out ATP. e.g. muscle movements, neurotransmission, heart beats and various chemical reactions in the body all are carried out with the help of ATP.

In animals ATP is produced from the breakdown of glucose in the cellular respiration, glucose is obtained from the diet we take in. In plants ATP is generated from the process of photosynthesis. The source of energy within ATP is phosphate bonds, the breakdown of one phosphate bond while conversion of ATP into ADP produces or releases 30.6 KJ/mole of energy.

Which type of ovarian follicle contains a secondary oocyte?

Illusion [34]

I think it is the secondary ovarian follicle that contains the secondary oocyte.The stages of the ovarian cycle that the follicle will go through includes; a primary follicle contains an oocyte and begins producing estrogen. Then the secondary oocyte contains a secondary oocyte and produces estrogen and some progesterone, then the graafian follicle develops and the secondary oocyte is released a process we call ovulation. the corpus luteum produces progesterone and some estrogen and lastly the corpus luteum degenerates.

A recently discovered enzyme is found to have maximum activity in a pH range of 6-8. It is thought that histidine and cysteine r

goldenfox [79]

Answer:

Cysteine

Explanation:

<u>Determine the Amino acid that is primarily involved in Binding </u>

The Amino acid that is primarily involved in Binding is Cysteine. while the other Amino acid ( i.e. Histidine ) will be involved in Catalysis.

since the enzyme is functional at pH 6 to 8. and Cysteine has a pH of 5, it should be deprotonated and used primarily for Binding .
