fiasKO [112]

Answer:

used to complete the glicolisis process

Explanation:

A glucose molecule will generate the necessary energy to the body to compete their own metabolic processes.

At the begging of the process, the glucose change into 2 molecules of gliceraldehyde 3 - phosphate. In this first process the glucose molecule consume 2 molecules of ATP (the energetic molecule).

After this first process, the aldehyde turns into piruvate, during this process, there is produced 2 molecules of ATP, so it is producing chemical energy.

If during this process the cell need to enter into another metabolic process (pentose ways) then the gain of ATP deplets.

Write some sentences about Respiration in your own words
weeeeeb [17]

Answer:

Reluctantly she pulled away, her pulse and respiration in a race.

Its function is less that of respiration than of FIG

Terrestrial plants have a gaseous interchange of oxygen and carbon dioxide which is necessary for respiration and feeding.

The least wind raises clouds of fine dust, which fill the air, render it so opaque as to obscure the noonday sun, and make respiration difficult.

Calculate the heat change in calories for melting 65 g of ice at 0 ∘c.
Genrish500 [490]

When ice melts, the physicals state changes from solid to liquid. The energy or the heat required (q) required to change a unit mass (m) of a substance from solid to liquid is known as the enthalpy or heat of fusion (ΔHf). The variables; q, m and ΔHf are related as:

q = m * ΔHf

the mass of ice m = 65 g

the heat of fusion of water at 0C = ΔHf = 334 J/g

Therefore: q = 65 g * 334 J/g = 21710 J

Now:

4.184 J = 1 cal

which implies that: 21710 J = 1 cal * 21710 J/4.184 J = 5188.8 cal

Hence the heat required is 5188.8 cal or 5.2 Kcal (approx)
