List 3 cellular components involved in metabolism that are influenced by temperature
stiv31 [10]

The three cellular components, which takes part in the process of metabolism and are affected by the modifications in temperature are ribosomes, cell membrane, and enzymes.

All these are formed of a certain type of protein, which can become denatured when exposed to high enough heat or stop gets functioning at too low temperature. The high temperature can disrupt the non-polar hydrophobic interactions and hydrogen bonds. This takes place as heat enhances the kinetic energy and makes the molecules to throb so briskly and viciously that the bonds get disordered.

If it takes 98.8 kcals to break one C--H found in an organic molecule, how many kcals does it take
steposvetlana [31]

395.2kcal

Explanation:

Given parameters:

Energy required to break one C-H bond = 98.8kcals

Unknown:

Energy required to break methane = ?

Solution:

The bond dissociation energy is the heat energy absorbed in breaking a covalent bond in the gas phase to its constituents elements.

  Solving

    CH₄ has 4 C-H bonds

To break 1 C-H bond, 98.8kcals of energy was used,

To break 4 of the bonds; 4 x 98.8kcals will be used = 395.2kcal
