Complex carbohydrates require enzymes such as Salivary amylase, Pancreatic amylase, and Maltose for digestion.
I know that alcohol/ethanol is used as a growth stimulant and can be used in metabolism, thats one reason why the organism keeps pyruvate.
Correct answer: A) Extension
Extension is a physical position that occurs when angle between the bones and the limbs of joint increases.
It takes place when there is a contraction of muscles and bones move the joint from a bent to a straight position, it is opposite of flexion, in which the angle between the bones and the limb at the joint decreases.
Example: During straightening of the leg, the angle between the tibia and femur increases, which shows extension has taken place.
When oxygen is scarce, pyruvic acid can accumulate and is converted to carbon dioxide and ethanol which causes formation of pyruvate to yield acetaldehyde
