|
a reactant in cellular respiration, the process that breaks down sugar and other foo molecules and generates ATP |
Oxygen |
|
|
____ and _____ provide energy for life |
photosynthesis and cellular respiration |
|
|
in cellular respiration, ____ is broken down to carbon dioxide and water |
sugar |
|
|
an exergonic (energy-releasing) process that transfers energy from glucose to form ATP |
cellular respiration |
|
|
provides energy for body maintenance and voluntary activities |
cellular respiration |
|
|
what is required to maintain a healthy weight? |
a balance of energy intake and expenditure |
|
|
. |
NADH passes electrons to an electron transport chain. Energy is released as electrons “fall” from carrier to carrier and finally O2 (oxygen) |
|
|
where does the glycolysis occur? |
in the cytosol |
|
|
. |
glycolysis begins cellular respiration and break down glucose into two molecules of a three-carbon compound called pyruvate |
|
|
during stage 2 of cellular respiration, where does pyruvate oxidation and the citric acid cycle take place in? |
mitochondria |
|
|
the oxidation of pyruvate yields |
acetyl CoA, Co2, and NADH |
|
|
. |
in mitochondria, electrons from NADH AND FADH2 are passed down the electron transport chain to O2 which picks up H+ to form water |
|
|
. |
in chemiosmosis, the H+ gradient drives H+ back through the enzyme complex ATP synthase in the inner membrane, synthesizing ATP |
|
|
where can you find brown fats at ? |
mitochondria |
|
|
what does ion channels do? |
•allow H+ flow freely across the membrane •dissipate the H+ gradient that the electron transport chain produced, which does not allow ATP synthase to make ATP |
|
|
substrate-level phosphorylation and oxidative phosphorylation produce up to |
32 ATP |
