Term
where does energy come from |
|
Definition
sun
sun(energy) +CO2 +H2O= photosynthesis
oxygen and glucose comes out |
|
|
Term
how is metabolism stored? |
|
Definition
-glucose: in bonds, all cells metabolize glucose for energy
|

Term
cellular energy metabolism
how is it metabolized?
|
|
Definition
-input is glucose(reactant)
1)glycolosis
2)respiration(w/O2) 2)fermentation(no O2)
cytoplasm
-output is {energy+O2+H2O}

Definition
sequence of reactions that can be grouped in two major processes |
|
|
Term
glycolosis
1st major process |
|
Definition
glucose activation- energy goes in |
|
|
Term
glycolosis
2nd major process |
|
Definition
energy harvest- energy goes out |

summary:
1 glucose+ 1 ATP yields 2 pyuruvate+2 NADH
|
|
|
Term
|
Definition
occurs in mitochondria in eukaryotes
pyruvate is transported from cytoplasm to mitochondrial matrix |
|
|
Term
three stages of respiration
|
|
Definition
1. pyruvate broken down, release energy and CO2 in the matrix
2. high energy electrons travel through the electron transport chain in the inner membrane
3. chemlosmosis generate ATP |
|
|
Term
cellular respiration
stage 1 |
|
Definition
stage 1: pyruvate is broken down, releasing energy and CO2
1a. formation of acetyl CoA in matrix
input of the krebs cycle
-CO2 released
-2 high energy electrons + a hydrogen ion +NADH 2/glucose |
