Answer:
yeah its newton's third law
Explanation:
Answer:
Light receptors within the eye transmit messages to the brain, which produces the familiar sensations of color. The surface of an object reflects some colors and absorbs all the others. We perceive only the reflected colors.
Explanation:
go.ogle :)
Answer:
The lock-and-key model:
c. Enzyme active site has a rigid structure complementary
The induced-fit model:
a. Enzyme conformation changes when it binds the substrate so the active site fits the substrate.
Common to both The lock-and-key model and The induced-fit model:
b. Substrate binds to the enzyme at the active site, forming an enzyme-substrate complex.
d. Substrate binds to the enzyme through non-covalent interactions
Explanation:
Generally, the catalytic power of enzymes are due to transient covalent bonds formed between an enzyme's catalytic functional group and a substrate as well as non-covalent interactions between substrate and enzyme which lowers the activation energy of the reaction. This applies to both the lock-and-key model as well as induced-fit mode of enzyme catalysis.
The lock and key model of enzyme catalysis and specificity proposes that enzymes are structurally complementary to their substrates such that they fit like a lock and key. This complementary nature of the enzyme and its substrates ensures that only a substrate that is complementary to the enzyme's active site can bind to it for catalysis to proceed. this is known as the specificity of an enzyme to a particular substrate.
The induced-fit mode proposes that binding of substrate to the active site of an enzyme induces conformational changes in the enzyme which better positions various functional groups on the enzyme into the proper position to catalyse the reaction.
A. solutions and colloids
Convection currents in air
Explanation:
The convection currents in air tends to blow out winds towards the water at night.
Convection is a mode of heat transfer commonly found in fluids.
It involves the movement of the particles due to differences in temperature and density of the air.
- The land and water heats at different rate.
- The land absorbs and loses heat quickly because it is a good conductor of heat.
- At night, the shore area is cold.
- The air around is very dense and close to the surface.
- This air mass moves towards the surface of the ocean.
- The ocean has high specific heat capacity and takes a long time to heat and cool.
- At night, as it is loosing heat, the air around warms up and rises shifting land ward.
- This movement of cold and dense air from land and the attendant movement of warm air to the land sets up convection currents in the air.
