Answer: Carbon monoxide
Explanation:
Carbon monoxide is a gas that is tasteless, colorless, and odorless, that is formed when wood, charcoal, gasoline is burnt.
When breathed in, carbon monoxide is harmful as it displaces the oxygen that is in the blood and this leads to the deprivation of the brain and other vital parts of the body of the oxygen that's is required for daily functioning.
Exposure to carbon monoxide is most likely affected cell differentiation in the growing embryo. When the pregnant woman inhales smoke, this affects the oxygen in the baby's bloodstream as it's being replaced by carbon monoxide and there's shortage of oxygen.
This affects the cell differentiation in the growing embryo and can lead to the child been born prematurely and can also lead to severe asthma like symptoms.
Answer:
If you add sucrose to catalase when testing for reactivity, do you expect to see a reaction?
Multiple Choice No, because catalase is specific to hydrogen peroxide. Yes, because catalase is an enzyme that increases any reaction rate. No, because catalase is specific to sucrose.
Explanation:
The nurse should evaluate how the child breathes through the nose. The child can still have swelling and stuffiness for several months. The child may have a different voice that is less nasal. There should be no bleeding from the nose or eyes.
Answer:
(C) Enzyme does not need to contact with substrate to assume its active form.
Explanation:
a) The activity of an enzyme can be increased upto certain temperature known as optimum temperature after that tepmerature will damage the enzyme.
b) The number of substrate molecule converted by one molecule of enzyme in one second is called its turn over rate, which may varry from 0.5-600000.
C) Enzymes does not need to contact with substrate to assume its active form. They just accelerate the reaction by lowering the activation energy. Enzyme binds to substrate through active stite and both changes structures slightly to best fit.(Induce fit model)
- Enzyme + Sbstrate → enzyme substrate complex→ Enzyme + Product
D) Some enzymes are inactive known as apoenzyme and they need a non-protein part such as coenzyme or cofactor to become active which is known as holoenzyme.
Most fish exchange gases using gills on either side of the pharynx (throat). Gills are tissues which consist of threadlike protein structures called filaments. These filaments have many functions including the transfer of ions and water, as well as the exchange of oxygen, carbon dioxide, acids and ammonia.
