Answer:
Lactase and Carbonic anhydrase are enzymes;These are organic catalyst (proteins) that speed up the rate of organic chemical reactions,in living organism.They acts on the organic reactions by reducing the activation energy for the reaction to occur,but remain unchanged at the end of the reaction.
Explanation:
Lactose is an enzyme in the small intestine needed for the break down of Lactose,a diasaccharides to glucose and galactose.it is acts in the brush borders for this to occur.
Carbonic anhydrase is an enzyme in the cytoplasm needed for the the catalysis of C02 with H20 to form Carbonic acid(H2CO3),protons, and hydrogen carbonate in a reversible reactions.
The catalysis is needed for regulation of blood pH during respiration.
As stated up,molecules of catalyst do not change in the organic chemcial raxction they act upon.Rather they lower the activation energy for the faster completion of the rate of reaction.
Therefore in the question above the amount of the catalayst will remain the same it was at the beginning of the reaction.This is the major properties of catalysts.
Answer:
this would be B
Explanation:
a oceanic crust is denser than a continental crust
Answer:
air
Explanation:
Of the three phases of matter (gas, liquid, and solid), sound waves travel the slowest through gases, faster through liquids, and fastest through solids.
Many autotrophs make food through the
process of photosynthesis, in which light energy from the sun is changed
to chemical energy that is stored in glucose. All organisms use cellular respiration to break down glucose, release its energy, and make ATP. Autotrophs are also called producers. They produce food not only for themselves but for all other living things as well (which are known as consumers). This is why autotrophs form the basis of food chains.
Yes, autotrophs need to perform cellular respiration.
Answer:D
Explanation: shivering occurs when someone is cold and vasoconstriction is when the blood vessels close to the skin and the veins closer to the skin surface constrict as a result of dat air doesn’t enter the body
