One group of reptiles, characterized by the fossil Archaeopteryx, led to the evolution of birds. The correct answer is birds
Mouth, pharynx, esophagus
Answer and Explanation: In enzyme kinetics, one constant describing enzyme activity is <em>Maximal Velocity</em> (Vmax). It indicates how fast an enzyme can catalyze the reaction. It is dependent on substrate concentration.
As the muscle is an organ which needs a great amount of energy, the enzyme glycogen phosphorilase is very active on the organ, compared to the liver, where glicose is stored. So, the Vmax of glycogen phosphorylase expressed in muscle is faster than when expressed in the liver, means the enzyme in muscle has a bigger concentration of substrate and therefore will reach Vmax faster, i.e. will be significantly larger.
Hydrogen isn’t one of the primary macronutrients
It is usually acetic acid that nature likes to make lipids out of.
