|
|
what 3 things do cells need in order to function? |
source of carbon source of energy source of electrons |
|
|
Why do cells need a carbon source |
because it is the fundamental building block for all organic molecules (carbohydrates, proteins, lipids, nucleic acids) |
|
|
Why do we need an electron source |
essential part of energy metabolism and because they are needed synthesis of cellular componets |
|
|
Why do we need a energy source |
because it is needed for processes such as transport, movement, and synthesis of cellular componets. |
|
|

substrates |
|
|
___________________ is a series of small steps or chemical reactions strung together where the product of 1 reactions becomes the substrate of the next |
metabolic pathway |
|
|
These type of organisms obtain their carbon source by eating organic molecules such as sugars, fats, and proteins |
heterotrophs |
|
|
when oxygen is used in cellular respiration it is called |
aerobic respiration |
|
|
This step of cellular respiration is simply put as the oxidation of glucose (removing electrons) to 2 pyruvic acids |
