HELP ASAP use the particle theory to explain why hot chocolate powder dissolves more rapidly in hot water than cold water

Biology

Answer:

To dissolve, solvent particles must come in contact with solvent particles. Particles of hot water are moving much more rapidly than particles of cold water. Hence, in hot water more water particles will come in contact with hot chocolate powder than in cold water, resulting in faster dissolving.

Aminolevulinate dehydratase (ALAD ) is an enzyme that relies on zinc as a coenzyme. A zinc ion binds to the ALAD active site, wh
slavikrds [6]

Answer:

The correct option is C. It changes the three-dimensional structure of the active site so that ALAD is no longer compatible with its substrate.

Explanation:

Co-factors are molecules that are required by an enzyme to perform its function of catalysis. If a wrong co-factor binds to the enzyme then it will change the three-dimensional structure of the enzyme and the substrate will no longer fit into the enzyme. Hence, Option C is the best choice that explains the inhibition of ALAD.

Other options are false because :

Option A: The wrong co factor will not affect the substrate nor will it make it compatible for ALAD's active site.

Option B:  The wrong factor doesn't change the amino acid sequence of the protein or enzyme, rather it changes the three dimensional structure of the enzyme.

Option D : The wrong co factor won't allow the reaction to proceed at a faster rate, rather it will inhibit the reaction.

Why are accessory pigments like carotene & xanthophyll necessary to have in
Kruka [31]

Answer:

The accessory pigments like carotene & xanthophyll necessary to have in green plants is chlorophyll

Explanation:

Various pigments present in the plants helps in the absorption of the light, at photosynthesis. They acts as helpers to the plants. Chlorophyll helps in the green plants for absorption of light through which they can prepare their own food. The electrons in the molecular level of chemical structure of the pigment moves at certain energy levels. The chlorophyll is again divided into different types i.e. chlorophyll a,b,c,d. In case of plants chlorophyll a and chlorophyll b are the most important.
