Answer:

A)glucose is broken down into two pyruvate molecules

The statement below correctly describes the process of glycolysis, glucose is broken down into two pyruvate molecules. The correct option is A.

Glycolysis is the process in which glucose is broken down to produce two molecules of pyruvic acid, which also releases energy. This process can be carried out without the help of oxygen, thus an anaerobic reaction. This process is carried out in the cytoplasm.

For the cell to use as energy, glycolysis results in a net gain of two pyruvate molecules, two ATP molecules, and two NADH molecules. Following the conversion of glucose to pyruvate, the Krebs Cycle is connected to the glycolysis pathway, where additional ATP will be produced to meet the energy requirements of the cell.

Therefore, the correct option is A.

The similarities between facilitated diffusion and active transport by a protein pump are firstly facilitated diffusion and active transport are two membrane transport mechanisms, which transport molecules across the plasma membrane, secondly transmembrane proteins are involved in both facilitated diffusion and active transport.

The differences between them are facilitated diffusion takes place down the gradient of concentration. active transport takes place toward the gradient of concentration. Facilitated diffusion is a passive method and needs no energy. An active method is an active transport.

What do you understand by facilitated diffusion?

"Facilitated diffusion is the passive movement of molecules along the concentration gradient. It is a selective process."

What do you understand by active transport?

"Active Transport is defined as a process that involves the movement of molecules from a region of lower concentration to a region of higher concentration against a gradient or an obstacle with the use of external energy."

What is a protein pump?

"Protein pump– a kind of protein that is capable of pumping out compounds that could pose a threat to the cell."

The correct list of greenhouse gases is: carbon dioxide, nitrous oxide, methane.

Greenhouse gases are gases capable of trapping heat in their bonds and releasing it into the atmosphere.

Greenhouse gases are the major cause of global warming, which is the increase in the average temperature of the atmosphere.

Greenhouse gases include the following: carbon dioxide (CO2), methane (CH4), nitrous oxide (NO2), sulfur dioxide (SO2) etc.

Answer:

Because of its high electronegativity.

Explanation:

Fluorine has ability to pull the electron from the lithium because of its high electronegativity.

We know that as we move from left to right in periodic table the number of valance electrons in an atom increase. The atomic size tend to decrease in same period of periodic table because the electrons are added with in the same shell. When the electron are added, at the same time protons are also added in the nucleus. The positive charge is going to increase and this charge is greater in effect than the charge of electrons. This effect lead to the greater nuclear attraction. The electrons are pull towards the nucleus and valance shell get closer to the nucleus. As a result of this greater nuclear attraction atomic radius decreases and electronegativity increases. AS lithium is present on left side of period 2 and fluorine is present on right side of same period. Fluorine is more electronegative while lithium is more electropositive thus fluorine pull the electron from lithium when they combine and form anion while lithium loses its valence electrons and form cation.
