Metabolism Ans✓✓✓Sum of all chemical reactions that occur in the
body
What are two types of metabolic reactions? Ans✓✓✓-Anabolic
-Catabolic
What is bioenergetics? Ans✓✓✓Metabolic process of converting energy
from food (macronutrients into biologically usable energy)
What are endergonic reactions? Ans✓✓✓Reactions that require energy
added
What are exergonic reactions? Ans✓✓✓Reactions that give off energy
What are three high energy bonds? Ans✓✓✓Endergonic Reactions
Exergonic Reactions
Coupled Reactions
Oxidative-Reduction Reactions are always what type of reaction?
Ans✓✓✓Coupled Reactions
,What is Activation Energy? Ans✓✓✓The amount of energy required for
a reaction to begin
How do enzymes influence activation energy? Ans✓✓✓-Lowers
activation energy, therefor reaction can occur easier/quicker
What happens to cells if they do not receive sufficient ATP? Ans✓✓✓-
They cannot function, therefor they will die.
What does Adenosine Triphosphate stand for? Ans✓✓✓ATP
What is the Adenosine Trisphosphate formula? Ans✓✓✓ATP--> ADP +
Pi + Energy
What are the ATP production Pathways? Ans✓✓✓1) Phosphocreatine
Breakdown
2) Glycolysis
3) Oxidative Formation
What happens to ATP during Phosphocreatine Breakdown at the onset
of exercise? Ans✓✓✓ATP is broken down rapidly at the onset of
exercise
What replenishes ATP during Phosphocreatine Breakdown?
Ans✓✓✓PCr! There is more PCr reserves than ATP in the body. PCr is
, used to replenish ATP, keeping ATP levels high, until both are
depleated.
What is the Phosphocreatine Breakdown formula? Ans✓✓✓PC + ADP -
--> ATP + C
How many reactions take place during Phosphocreatine Breakdown?
Ans✓✓✓One reaction therefor it is the fastest ATP production pathway
(0-14 seconds), however it produces the lease amount of ATP.
Where does Glycolysis take place? Ans✓✓✓Within the Sarcoplasm of
the muscle cell
What is the ATP net gain from Glycolysis? Ans✓✓✓2 ATP
How many reactions occur in Glycolysis? Ans✓✓✓10 coupled reactions
therefor takes between 30 seconds - 2 minutes.
Of the 10 steps in Glycolysis which ones are energy investment and
energy generation? Ans✓✓✓Top 1/2: Energy Investment
Bottom 1/2: Energy Generation
In Glycolysis what do we start with? Ans✓✓✓One Glucose molecule
