Answer:
The correct answer is: catalysts lower the activation energy of the reaction.
Explanation:
Catalysts are substances that in our bodies are commonly represented by enzymes (specialized proteins) and that are used in chemical reactions to speed them up.
In order to achieve this, catalysts lower the activation energy of chemical reactions, which is a value of energy that must be obtained for the reaction to actually happen.
Catalysts are constantly used in our bodies and are responsible for the proper functioning of every organ. These catalysts can be used over and over again because they are not consumed in the reaction.
Molecules spread out. Molecules from places with high concentration to low concentration.
Answer:
1. TEF
2.RMR
3.TEA
Explanation:
The major components that contribute to the body daily expenditure are as follows
1. TEF(Thermal effect of feeding)
2.RMR( Resting metabolic rate )
3.TEA(Thermal effect of activity)
Generally resting metabolic rate consume 60 to 75% of energy for maintenance thwe body temperature.
When body is doing this some physical work then it is called activity related expenditure.
Answer: In females, most of gametogenesis occurs during embryonic development. Primordial germ cells migrate into the ovaries at week 4 of development and differentiate into oogonia (46,2N).
