Metabolism
• The scientific term for obtaining
and using energy
Cellular respiration
• the process through which our cells get the
energy to perform their functions. Since all
living things are made of cells, and all cells
need energy to perform life's functions,
cellular respiration is necessary for all living
things.
There are two types of cellular
respiration: aerobic and anaerobic
• During aerobic respiration, oxygen is present,
and this results in a larger amount of energy.
Even though anaerobic cellular respiration
lacks the presence of oxygen, it is still able to
produce energy, just smaller amounts of it.
This process is called fermentation.
Aerobic respiration • the process by which a cell uses O2 to "burn"
molecules and release energy
ATP
• Is considered to be the 'energy currency' of cells.
During cellular respiration, food molecules are
broken down from sugar molecules to energy
molecules.
• All organisms produce ATP by releasing energy
stored in glucose and other sugars.
• Plants make ATP during photosynthesis.
• All other organisms, including plants, must
produce ATP by breaking down molecules such as
glucose.

glycolosis
• (glyco = sugar; lysis = breaking)
• Goal: break glucose down to form two
pyruvates
• Who: all life on earth performs glyclolysis
• Where: the cytoplasm
Fermentation
• is a metabolic process that converts sugar to
acids, gases or alcohol. It occurs in yeast and
bacteria, but also in oxygen-starved muscle
cells, as in the case of lactic acid
fermentation.
Variables
• Independent – The thing you change. There
can only be one. It is listed first on a data
table.
• Dependent – Can be measured, can be more
than one. The “what happened”.
• Control – a constant, no changes made to it.
