Activation energy is required to start a chemical reaction. Activation energy is the energy needed to allow the reactant to react. Activation energy is measured in Joules (J).
Answer:O The final product of cellular respiration is electromagnetic radiation.
The energy conversion in cellular respiration takes place in the chloroplast.
The main source of chemical energy in cellular respiration is water.
Explanation:
After the star's outer layers are expelled, the density of the remaining material is typically too low to provide adequate energy to sustain the hydrogen-burning shell's nuclear temperatures, and the remaining star easily contracts to form a white dwarf (a star with a density equal to the Sun, but a diameter equal to the Sun).
Animals need to consume food in order to obtain energy (just like humans.
