Answer:
Molecules which move against the concentration gradient across the cell membrane employ the mechanism of active transportation.
Explanation:
Normally, permitted molecules moves across the cell membrane of the cell by the process of diffusion and osmosis. This is used when molecules move from hypertonic region to hypotonic region (if ions) and hypotonic to hypertonic (if water). This is a passive transportation which do not require the expense of energy from the cell.
In contrast, when molecules move in or out of the cell against their concentration gradient, that is ions moving from hypotonic region to hypertonic region, they implore the expense of energy in form of adenosine triphosphate (ATP), and the involvement of the membrane carrier proteins. This is called active transport.
Vestigial structures. These are structural elements that once served a purpose but as the organism evolved now serves no purpose.
Glycolysis is the breakdown of glucose where the final product is pyruvate, glycogenesis is the process of formation of glycogen and the product in first step is glucose-1-phosphate. Glycogenolysis is the process in which the initial reactant is glycogen, and gluconeogenesis is the formation of glucose from pyruvate.
<h3>What is glycogen?</h3>
Glycogen is a type of carbohydrate that is stored in the liver and gets converted into glucose in emergency situations.
It is formed by the process of glycogenesis and the first-step product is glucose-1-phosphate.
Glycolysis is the breakdown of glucose where the final product is pyruvate.
Glycogenolysis is the process in which have initial reactant glycogen and occurs when brain and muscle require immediate energy.
Gluconeogenesis is the formation of glucose from pyruvate.
Thus, these were the explanation for glycolysis, glycogenesis, glycogenolysis and gluconeogenesis.

Answer:
The picture is upside down
Explanation:
Plants use sugars and mineral from the sail to make food and use the energy from the sun to create the sugars used to make the food. They also use the carbon dioxide from the air to help create the food.
