This is a reaction going on in your muscle cells right this very minute:The enzyme triose phosphate isomerase catalyzes this rea
Arisa [49]

Explanation:

The given reaction is as follows.

       E + S \rightleftharpoons ES \xrightarrow[]{k_{2}} E + P

Here, [E] = triose phosphate isomerase = 0.1 nm = 0.1 \times 10^{-9}m

         [S] = Dihydroxy acetone phosphate = 5 \mu m = 5 \times 10^{-6}m

         [P] = Glyceraldehyde-3-phosphate = 2 \mu m = 2 \times 10^{-6}m

Therefore, velocity of the reaction will be as follows.

          v = \frac{d[P]}{dt} = \frac{K_{2}[E][S]}{K_{M} + [S]}

where, K_{M} = Michaelic menten constant = \frac{K_{1} + K_{2}}{K_{1}}

            v = \frac{900 \times 0.1 \times 10^{-9}m \times 5 \times 10^{-6}m}{10^{-5} + 5 \times 10^{-6}}

               = 30 \times 10^{-9} m

or,            = 30 nm/s

Hence, we can conclude that the actual velocity of the forward reaction under physiologic conditions if KM = 10 μM is 30 nm/s.

Dana is trying to determine if an unknown sample is a pure substance or not. The sample has a cloudy white color, and it seems e
Firdavs [7]

Answer:

Dana filtered the sample and larger granules of the sample were left behind.

Explanation:

If a substance is pure, it will have a uniform composition throughout. It will not separate into particles of various sizes.

One of the characteristics of pure substances is that they are homogeneous. A mixture is definitely made up of particles of various sizes.

Since the particles was filtered and larger granules were left behind, the sample has been separated by a physical method (filtration). Only a mixture can be separated by physical methods. It is not a pure substance.

Breaking larger molecules into smaller molecules and carbon
ella [17]

Answer: catabolism

Explanation:

Catabolism refers to the set of metabolic pathways which is necessary for the breaking down of molecules into smaller units. This is then oxidized for the release of energy or can be used to perform other anabolic reactions.

Catabolism is regarded as the opposite direction of anabolism which is simply the building-up of molecules. It should be noted that anabolism and catabolism work together in every living organisms and perform functions such as the production of energy and the repair of cells.

Calculate the molar solubility of ca(io3)2 in each solution below. the ksp of calcium iodate is7.1 × 10−7.
e-lub [12.9K]
In order to find the answer, use an ICE chart:

Ca(IO3)2...Ca2+......IO3- 
<span>some.......0..........0 </span>
<span>less.......+x......+2x </span>
<span>less........x.........2x 
</span>
<span>Ca(IO₃)₂ ⇄ Ca⁺² + 2 IO⁻³
</span>
K sp = [Ca⁺²][IO₃⁻]²
K sp = (x) (2 x)² = 4 x³
7.1 x 10⁻⁷ = 4 x³
<span>x = molar solubility = 5.6 x 10</span>⁻³ M

The answer is 5.6 x 10 ^ 3 M. (molar solubility)

What is the definition of law of chemical combination??
Jet001 [13]

Answer:

In simple terms, this law states that matter can neither be created nor destroyed. In other words, the total mass, that is, the sum of mass of reacting mixture and the products formed remains constant.
