Question

cellular respiration: how do organisms get energy from food?
biology study guide
energy from food model ideas
new model ideas
living things rearrange food (specifically glucose - c₆h₁₂o₆) and o₂ into co₂ and h₂o.
(c₆h₁₂o₆ + o₂) have higher energy than (co₂ + h₂o) so this rearrangement releases energy.

• the rearrangements occur in a series of steps rather than all at once.
• collectively the reactions are called cellular respiration.
• usable cellular energy is released in the form of atp.

matter from food
some of this matter is really taken in for energy. it is rearranged to obtain energy in a reaction called
cellular respiration. the products are expelled from the body as carbon dioxide and water (co₂ ·
h₂o).

• some of the matter we take in is used to build proteins, fats and complex carbs that form cells of

body structures.

• excess food not used for energy or building materials is converted to fat and stored.

what is the overall reason for cellular respiration? why do we do it?
which of the above energy diagrams above is similar to cellular respiration?
which of the above energy diagrams is similar to photosynthesis?

Explanation:

The problem is about cellular respiration, which is a biological process. The subfield under Natural Science that deals with living organisms and their processes is Biology. So the most applicable subfield is Biology.

Answer:

Natural Science - Biology
