Muscle Activity Flashcards
During resting periods of muscle activity:
What is the “fate” of glucose (what does it become)?
Glucose is stored as glycogen in the muscle cell.
During resting periods of muscle activity:Are you using or producing ATP here?
Using ATP to convert Creatine to Creating Phosphate, and glucose to glycogen.
During resting periods of muscle activity:Are you producing or using CP?
Producing Creatine Phosphate storage.
During resting periods of muscle activity:Are mitochondria making ATP and what happens to any “excess” ATP?
Mitochondria is making ATP, and the excess is used to create Creatine Phosphate and store glycogen.
During resting periods of muscle activity:What are the mitochondria using to produce ATP?
Mitochondria is using Fatty acids and O2.
During moderate levels of activity:
What happens to glycogen?
Glycogen is being converted to glucose
During moderate levels of activity: What does glucose become – what is its “fate?”
Glucose becomes Pyruvic Acid
During moderate levels of activity: What are the mitochondria using to produce ATP?
Mitochondria are using Fatty acids, O2, and Pyruvic acid
During moderate levels of activity: Does glucose go directly into the mitochondria?
No, Pyruvic acid goes straight into the mitochondria
During moderate levels of activity: How many ATP are coming from glycolysis (glucose to pyruvic acid) directly
2 ATP from glycolysis
During moderate levels of activity: How many ATP come from pyruvic acid being used by the mitochondria?
34 ATP come from Pyruvic acid
During “peak” physical activity which metabolic pathway is our primary source of ATP production?
Glucose is the fuel, and glycolysis is the metabolic pathway.
What substance is not being used efficiently by the mitochondria?
Pyruvic acid is not used efficiently
Why is this happening?
Not enough O2
What happens to this substance that is building up in the muscle cell?
Pyruvic acid is being converted to latic acid and being sent to the liver by the bloodstream.
