What's the energy currency in the body?
ATP is produced by oxidation of which macro-molecules?
Proteins, Carbohydrates, and Fats
(ADP + Pi --> ATP).
What consumes ATP?
Reactions necessary for life
(ATP --> ADP + Pi)
Which chemical bond is a high energy bond?
Why must the supply of ATP be continuously replenished?
ATP can't be stored
What's the primary substrate used for ATP synthesis?
Which produces more ATP?
A. Aerobic metabolism
B. Anaerobic metabolism
There are 3 key processes involved in aerobic glucose metabolism:
The primary goal of glycolysis is to convert 1 molecule of -------- into two molecules of --------------
2 pyruvic acid
The primary goal of glycolysis is to convert 1 glucose to 2 pyruvic acid molecules. The fate of pyruvic acid depends on whether or not ---------- is available.
In the absence of oxygen, pyruvic acid is converted to ---------- in the cytoplasm
If oxygen is available, pyruvic acid is transported into
Net Gain ATP gain of Glycolysis
Next, 2 molecules of pyruvic acid are converted into 2 molecules of
Acetyl Coenzyme A
Which compound is produced in the Rapoport-Luebbering shunt about halfway through glycolysis?
The more glucose molecules that go through glycolysis
A. the more 2,3 DPG is produced
B. the fewer 2,3 DPG is produced
the more 2,3 DPG is produced
Where does the Krebs cycle take place?
Matrix of the mitochondria
Kreb's cycle begins with the reaction of which two molecules?
Acetyl coenzyme A
Kreb's cycle begins with the reaction of oxaloacetic acid and Acetyl coenzyme A react to produce
Kreb's cycle ends with the production of which two molecules?
True or False
Oxaloacetic acid produced at the end of one Kreb's cycle is reused at the beginning of the next cycle
The primary goal of the Krebs Cycle (Citric Acid Cycle) is to produce a large quantity of
The large quantity of H+ ions produced during the Krebs Cycle (Citric Acid Cycle) is in the form of:
The primary goal of the Krebs Cycle (Citric Acid Cycle) is to produce a large quantity of H+ ions in the form of NADH. These are used in which process?
True or False
Only the products of Carbohydrate metabolism can also enter the Krebs cycle
Products of protein and lipid metabolism can also enter the Krebs cycle
Krebs Cycle (Citric Acid Cycle) net ATP gain is:
The primary goals of glycolysis and Krebs cycle is to
A. liberate hydrogen from glucose
B. liberate carbon from glucose
liberate hydrogen from glucose
Before Oxidative Phosphorylation, what's the net gain of molecules of ATP for 1 molecule of glucose?
4 molecules of ATP
During Oxidative Phosphorylation NADH is split into which three entities?
NAD+, H+, and 2 electrons
During Oxidative Phosphorylation NADH is split into NAD+, H+, and 2 electrons. The electrons are fed into which mechanism?
