Compared to other more basic molecules, glucose is rather large. In order for glucose to enter the cell in the first place, the cell must actively transport it from outside the cell wall using special transport proteins. This is compared to a cell passively transporting molecules, where the molecules are small enough (or non polar) to pass through the cell membrane without any action from the cell itself.
Once the glucose is in the cell, there is no way to get out.

How many molecules of ATP are made from breaking down a molecule of glucose?
About 36 ATP molecules are produced from a single molecule of glucose. There are 2 pathways by which ATP is produced one is aerobic (in presence of oxygen) and other is anerobic (without oxygen). ATP is the energy rich molecule produced at diffferent levels when a glucose molecule undergoes breakdown into intermediate compounds through a long pathway called glycolysis which takesplace in mitochondria. A complex series of events follow in glycolysis, which involve transfer of important groups like phosphate, hydroxyl etc from or to the glucose molecule. thus ATP is produced as a result of these complex events and utilised in daily energy requirements.
When a sucrose molecule is decomposed to yield a glucose molecule and a fructose molecule?
This decomposition process involves breaking the glycosidic bond between glucose and fructose in the sucrose molecule. This hydrolysis reaction requires the addition of a water molecule to break the bond, resulting in the formation of glucose and fructose molecules.
Is glucose uncharged?
Yes, glucose is an uncharged molecule. It is a simple sugar with a molecular formula of C₆H₁₂O₆, consisting of carbon, hydrogen, and oxygen atoms. At physiological pH, glucose does not have any ionizable groups, which means it exists as a neutral molecule without a net charge.
What will happen if the concentration of glucose in the water outside the cell is higher than the concentration inside?
Water will move out of the cell. Glucose will not move into the cell without the help of a helper molecule. Glucose molecules will diffuse into the cell.(APEX)
Which componet of a nucleotide present within a DNA molecule could be removed without breaking the polynucleotide chain?
The phosphate group can be removed from a nucleotide without breaking the polynucleotide chain within a DNA molecule. The phosphate group is attached to the 5' carbon of the sugar molecule in a nucleotide through a phosphodiester bond, which does not affect the backbone of the DNA chain when cleaved.

Water will move out of the cell. Glucose will not move into the cell without the help of a helper molecule. Glucose molecules will diffuse into the cell.(APEX)
What molecule CANNOT be generated by a chloroplast that has been deprived of CO2?
A chloroplast deprived of CO2 cannot generate glucose, as glucose is produced during the Calvin cycle through the conversion of CO2 to glucose. Without CO2, the chloroplast cannot fix carbon and proceed with the Calvin cycle to produce glucose.
What is A large glucose molecule requires facilitated diffusion but an oxygen molecule referring to?
A large glucose molecule requires facilitated diffusion because it is too big to pass through the cell membrane without assistance from transport proteins. In contrast, an oxygen molecule is small enough to diffuse freely across the cell membrane through simple diffusion due to its size and hydrophobic nature.
Which component of a nucleotide present within a DNA molecule could be removed without breaking the polynucleotide chain?
all i know is that its not phosphate
What is the difference between conformation and configuration in the context of molecular structures?
Conformation refers to the temporary arrangement of atoms in a molecule, which can change without breaking any bonds. Configuration, on the other hand, is the fixed arrangement of atoms in a molecule, which can only be changed by breaking and reforming bonds.
What is a example of a molecule that uses a channel protein?
An example of a molecule that uses a channel protein is glucose. Glucose transporters, specifically GLUT proteins, facilitate the passive transport of glucose across the cell membrane through channel proteins, allowing cells to absorb glucose efficiently without the need for energy. This process is crucial for maintaining energy levels in cells, particularly in insulin-sensitive tissues like muscle and fat.
