Chemical Basis of Cellular Respiration Allows for the extraction of energy from sugars (i.e glucose) by slowing oxidizing it This process converts potential chemical energy into ATP (which can be used by a majority of reactions) C-H bonds (those found in glucose) are the primary energy bond found in organic molecules (i.e glucose, octane etc.)…
NADH and FADH2 carry electrons to the ETC Each become oxidized, losing two electrons to the ETC The Electron Transport Chain (ETC) Structure Located within the inner mitochondrial membrane Composed of various protein structures arranged in order of increasing electronegativity Ex. weakest electron attractor (NADH dehydrogenase) is at the beginning of the chain and the…
Carbohydrates are the first nutrient most organisms catabolise for energy, however, living things must metabolize other energy-rich nutrients to obtain energy in times of starvation Protein Catabolism – first digested into amino acids – amino groups are removed (deamination; amino group à ammonia [NH3]) – remaining portion of amino acid converted into various components of…
Energy – needed for: – movement – synthesis of complex compounds – active transport Food – provides energy needed by cells – broken down > heat (body heat, excess removed) chemical storage form Cellular Respiration – is the process by which chemical energy stored in food (usually glucose, but may be protein and lipids is…
