what are the products and reactants of respiration?

Question

does any body know what the products and reactants of respiration are? please help!! thanks

Answer 1

There are 4 phases of cellular respiration:
1. Glycolosis
2. Production of Acetyl CoA (aka--Transition Reaction and preparatory phase)
3. Krebs Cycle (aka--Citric Acid Cycle)
4. Electron Transport Chain

For Glycolysis: (Inputs)
2 ATP
1 glucose molecule C6H12O6
2 NAD+ (coenzyme) I think of these guys as taxis
2 ADP+P

For Glycolysis: (outputs)
2 pyruvic acid
2 NADH+H
4 ATP (only 2 net gain though)

For Preparatory Phase: (inputs)
2 pyruvic acid
2 NAD+
2 O2

For Preparatory Phase: (outputs)
2 Acetyl CoA
2 NADH+H
2 CO2

For Krebs Cycle: (inputs)
2 Acetyl CoA
6 NAD+
2 FAD (another coenzyme)
4 O2
2 ADP+P

For Krebs Cycle: (outputs)
6 NADH+H
2 FADH2
4 CO2
2 ATP

For Electron Transport Chain: (inputs)
10 NADH+H
2 FADH2
6 O2

For Electron Transport Chain: (outputs)
10 NAD+
2 FAD
6 H2O
34 ATP

End result is 36 to 38 ATP (ENERGY)

Answer 2

When you talk about products and reactants of respiration, you are most commonly talking about cellular respiration.

This is to say, you are talking about how a cell breaks down energy rich molecules to make ATP (the energy substrate of the cell).

So have a look at the wiki page on cellular respiration

Our cells take fats and sugars (eg glucose) - these are the reactants - and turn them into ATP (and some other co-enzymes) - these are the products

Answer 3

1 Glucose (C6H12O6) + 6 O2 -----> 6 CO2 + 6 H2O + 36ATP
