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

esidues are a part of the active site. Kinetic experiments of pH dependence in the wild type (WT) enzyme, as well as kinetic experiments at pH 7.0 in site-specific mutants of residues thought to be in the active site, showed the results below.
pH KM(mM) Kcat(s^-1)
5 0.14 15
7 0.12 332

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 .

VLD [36.1K]

Answer:

Option (D)

Explanation:

The entropy is usually defined as the measure of the total thermal energy of a system per unit temperature. This amount of energy is used in performing valuable work. In simple words, it can be said that entropy is related to the disorder or degree of randomness of a particular system. This entropy concept gives proper information regarding the direction along which natural change occurs and is frequently observed in many present-day events.

Thus, the correct answer is option (D).

anyanavicka [17]

Answer:

1. ridges and trenches (either answer is acceptable)

2. mid-atlanitc

3. subduction zone

4. molten

5. oceanic trenches

Explain:

6. Rocks in the ocean eventually get subducted back into earths mantle due to slab pull. New rocks form at mid-ocean ridges as ridge forces two plates to diverge.

What is the name of the photosynthetic process in which light energy is converted into chemical energy in ATP and NADPH
abruzzese [7]
Thus, light energy is initially converted to chemical energy in the form of two compounds: NADPH, a source of energized electrons ( "reducing power"); and ATP, the versatile energy currency o that the light reactions produce no sugar; that happens in the second stage of photosynthesis, the Calvin cycle.

When these muscles contract (during cold or fright), the slanted hair follicle is pulled upright, dimpling the skin surface with
inn [45]

The muscles that contract (during cold or fright), the slanted hair follicle is pulled upright, dimpling the skin surface with goosebumps are called arrector pili muscle.

The arrector pili muscle are tiny muscle that attaches to the base of the hair follicle at one end  and to the dermal tissue on the other end. When the body feels cold or fright the body generate heat and the arrector pili muscle contract all at once, that causes goosebumps on the skin.

The arrector pili muscle acts as the thermoregulator. Straight stand hair increases air trapping, so that the heat loss from the body decreases. The arrector pili muscle are mediated by the sympathetic nervous system.
