Some Questions bout Biology,plz answer?

Question

1.Give me as accurate as possible where the energy comes from with which we do efforts(example: running up the stairs , writing a text, ...)

2.How can our body adapt to a larger enery need coz of larger efforts?

3.What is the connection between running faster and breathing quicker?

4.On which organs of our body will regular and intensive sport exercises have an effect? Explain plz

Answer 1

1,all the energy used by us comes from burning the carbon and hydrogen in the food we eat making use of the oxygen we breath in
2.when more energy is required more oxygen is requires and
quicker should be the conversion of food into energy.here is where two things happen
we tend to breathe quicker
the secretion of adrenalin is increased

3.the faster you run,the quicker you will breathe for reasons cited above

4.the hormone secreting organs,sweat glands,heart,lungs
for reasons explained above

Answer 2

In general, the concept of energy refers to "the potential for causing changes". The word is used in several different contexts. The scientific use has a precise, well-defined meaning, whilst the many non-scientific uses often do not. (see here.)
In physics, energy is the ability to do work and has many different forms (potential, kinetic, electromagnetic, etc.) No matter what its form, physical energy has the same units as work; a force applied through a distance. The SI unit of energy, the joule, equals one newton applied through one meter, for example.

Your lungs have to work harder the faster you run.

Answer 3

okay, i got question # 3...

if we run fast, our breathing goes faster because of the oxgyen requirement in our body. it is our body's response to intense work outs ( such as running faster)
