How does a cell keep glucose from escaping without breaking down the molecule?

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.

What is to last a long time without breaking or wearing out?
escaping
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.
Without oxygen a cell can extract a net gain of only?
2 molecules of ATP from each glucose molecule.
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 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
Which componet of a nucleotide present within a DNA molecule could be removed without breaking the polynucleotide chain?
The part of a nucleotide that can be removed without breaking the chain is the thymine for DNA and the uracil for RNA. These two components are the nucleobases of a nucleotide.
What molecule can diffuse from the digestive tract into the human blood stream without first being digested?
Water, oxygen, and carbon dioxide can enter or leave a cell by diffusion without being digested.
Why is a critical resource for all living things?
without water we won't get the hydration we need and the glucose an dwater we need to under go respiration which is the breaking down of glucose or sugars to produce energy for the body. We take in oxygen glucose and water and the bi products are carbon dioxide and some water molecules.....this is why when you breathe on the window it gets foggy.
How many ATP molecules are produced from the kreb cycle?
directly, without using the electron transport chain there is one ATP per turn of the Krebs cycle, and two turns per glucose molecule.
What part of the skeletal can bend without breaking?
Cartilage can bend without breaking. It's the only part that can.
Should you eat glucose?
Glucose alone is not that healthy for you, but glucose is in most foods. You cannot live without glucose, so you should definitely eat foods containing glucose.
