Types of ATP regeneration

What is creatinine phosphate

A unique high energy substance stored in muscles

What is the use of creatine phosphate

It is tapped in to to regenerate ATP while other metabolic pathways adjust to the sudden high demand for ATP. It is used when we start to exercise vigorously and ATP demand sores

What does creatine phosapte and ADP yield? What is the enzyme in this reaction

ATP and creatine; creatine kinase is the enzyme

What occurs when creatine phosphate and ATP are exhausted

More ATP is generate by breaking down glucose obtained in the blood or glycogen stored in the muscles

What is glycolysis

The initial phase of glucose breakdown

Does glycolysis use oxygen

No, it is anaerobic

That does glycolysis produce

Two pyruvate acid molecules, which release enough energy to form small amounts of ATP. About 2 ATP per glucose

What happens to the pyruvic acid when oxygen is not readily available

It is converted into lactic acid

What is anaerobic glycolysis

1. Reaction that breaks down glucose without oxygen

2. Glucose is broken down to pyruvic acid to produce some ATP

3. Pyruvic acid is converted to lactic acid

4. Lactic acid produces muscle fatigue

Where does the lactic acid go

The blood carries the lactic acid to the liver.

Is the aerobic or anaerobic pathway more efficient

Aerobic. Anaerobic harvest about 5% the atp the aerobic does

Which pathway, aerobic or anaerobic, supplies energy for spurts of vigorous exercise

Anaerobic

Where does ATP come from during lighter and longer workouts

The aerobic pathways; aerobic respiration

What does aerobic respiration require?

Oxygen

Where does aerobic reposition occur

The mitochondria

How much ATP can be produced from aerobic respiration

About 32 ATP per glucose

Is anaerobic or aerobic respiration faster

Anaerobic

What pathway is used to supply energy for prolonged duration exercise

Aerobic pathway

What is aerobic endurance

The length of time muscles can contract using aerobic pathways

What is anaerobic threshold

When exercise intensity increases above the steady state aerobic metabolism and forces anaerobic pathways to kick in and provide ATP

What activities rely on entirely ATP and creatine phosphate

Lifting, short sprints, diving

What activities rely on anaerobic pathways for atp

Tennis, soccer, 100 m swim

What activities depend mainly on aerobic pathways

Long distance runs, like marathons

Do levels of creatine phosphate and ATP change much during prolonged exercise

No, it is a pay as you go system.
