Discuss the role of epinephrine on carbohydrate metabolism?
It is generally accepted that epinephrine promotes the breakdown of muscle glycogen to lactic acid and that this lactic acid is largely reconverted to glycogen by the liver.
Does Muscle glycogen cause muscle contraction?
no, lactic acid does
What is the by-product of incomplete glycogen breakdown in the absence of oxygen?
Lactic acid
The amount of oxygen liver cells require to react lactic acid to produce glucose or the glycogen glycogen is the?
oxygen debt
What type of muscle fiber breaks down lactic acid to produce energy?
The liver will extract lactic acid from the blood stream and convert it into glycogen, a reserve fuel type of energy.
How does the energy system recover?
The lactic acid energy system relies on the breakdown of glycogen to produce energy. As it does not require oxygen to break down glycogen a by-product called lactic acid is formed. If enough lactic acid is accumulated then the body begins to fatigue. To recover, the lactic acid requires oxygen. Once oxgen is present the lactic acid can be converted back to pyruvic acid which can once again be used to produce energy. Therefore to speed up recovery of the lactic system an "active"recovery at a low intencity is recommended. This then employs the use of the aerobic energy system which requires oxygen to be transported to the working muscles, and at the same time removing the fatiguing lactic acid.
The liver converts lactic acid to X which it then can convert to X for storage can you please tell me what are the two words that replace X mark?
The liver converts lactic acid to glucose, which it then can convert to glycogen for storage.
The amount of oxygen liver cells require to react lactic acid to produce glucose or the glycogen?
The amount of oxygen liver cells require to react lactic acid to produce glucose or the glycogen is the oxygen debt. Threshold stimulus is the minimal amount of energy required to contract a muscle fiber.
One type of fermentation in muscle cells produces?
Lactate (also known as lactic acid) and NAD+
Is lactic a base or an acid?
acid as in lactic acid?
What are the two main types of lactic acid?
Lactic acid has two optical isomers: L-lactic acid and D-lactic acid.
What are the products of lactic acid frementation?
Lactic acid (or lactate, which is the anion of lactic acid) is the product of lactic acid fermentation.
