Describe the role of ATP in aerobic respiration
|
It is what powers cellular work, is produced from the cycle. It is made by the breaking of ionic bonds
|
|
|
Describe the role of NAD+ & FAD
|
They are coenzymes and the carriers of H+ & e- electrons. FAD is not used in Glycolosis, but in CAC and ETC,; NAD is used all through the process.
|
|
|
What are the stages of respiration, what happens, and where in the cell?
|
(1: Glycolosis - the breaking of a glucose molecule into 2 pyruvate, generating 2 ATP; occurs in cytoplasm): (2:CAC - Acetyl CoA(groomed pyruvate) enters and looses 2 CO2, 2 NAD>NADH, 2 FAD>FADH generating 2 ATP); (3:OP - ETC & Chemiosmosis - NADH>NAD, FADH>FAD each loose H- electrons in stages/stairs and ea step produces ATP and finally generating water as a result. Chemiosmosis takes ATP synthase and pulls H- ions back into cell combining w ADP+P making more ATP, This cycle generates 38 ATP, Both 2nd & 3rd stage occur in Mitochrondia
|
|
|
What are the products of glycolosis, including energy carrying molecules?
|
2 pyruvate, 2ATP, 2 NADH, The 2 pyruvate give off CO2 and form Acetyl CoA with help from NAD
|
|
|
What are the products during CAC from ONE glucose and ONE pyruvate?
|
Glucose products - 2 CO2, 6 NADH, 2 FADH, & 2 ATP; Pyruvate products - 2 CO2, 3 NADH, 1 FADH, & 1 ATP
|
|
|
Describe how a H+ gradient is formed as electrons are moved along the ETC
|
In the electron transfers down the "stairs", H+ ions are moved across the gradient through transport proteins
|
|
|
Describe how the formation of a H+ gradient is coupled to the synthesis of ATP
|
The moving of molecules across the gradient help the production of ATP
|
|
|
Describe the role of Oxygen in aerobic respiration
|
Oxygen is the magnet that pulls the H+ electrons along the ETC to form water.
|
|
|
What are EXER- and ENDERgonic reactions?
|
Exergonic - is the release of energy to be stored as ATP; Endergonic - is the using of energy to break down of ATP
|
|
|
What are the #'s of products and reactants from each of the 3 stages of cellular respiration?
|
1) 2 pyruvate, 2 nadh, 2 atp, 2 CO2; 2) 2 atp, 6 nadh, 2 fadh; 2 co2 3) 30-34 atp
