Glucose is modified by particular reactions, and eventually splits into 2 3 carbon sugars, which interconvert between each other. These are modified further to produce pyruvate. Glycolysis literally means, "splitting sugars".

How does nutrients cross plasma membrane?
Things like oxygen, CO2 and lipids cross the membrane with simple diffusion. Water can cross the membrane with osmosis when the water moves through a channel protein in the plasma membrane. Glucose, potassium, sodium etc. moves through a carrier protein in the membrane with the process of active movement. In the process of active movement energy is needed and it is given by the glucose or ATP from the cell.
What do the veins of the leaf contain?
They contain xylem and phloem. Xylem moves water up and phloem moves glucose up or down.
What are the three examples of molecules that a cell would want to be able to move effectively across its membrane?
Oxygen: Cells need oxygen for cellular respiration and energy production. Oxygen moves across the cell membrane through passive diffusion to reach the mitochondria. Glucose: Glucose is a vital source of energy for cells. It requires transport proteins, such as glucose transporters, to move efficiently across the cell membrane. Water: Water is crucial for various cellular processes. It moves across the membrane through specialized channels called aquaporins, allowing cells to regulate their hydration levels and maintain homeostasis.
What does 'villi' have to do with respiration?
Glucose is absorbed from the food in our small intestine. Inside the small intestine we have small finger like structures called villi. The glucose is absorbed by the villi. The glucose is absorbed (moves through) the villi and enter our blood system. Glucose is transported by our blood to all the cells in our bodies. Respiration takes place in our cells (in the mitochondria of cells). Respiration is where glucose (our bodies fuel) combines with oxygen (we breath in) to give us ENERGY, carbon dioxide and water.
Where do plants get there glucose from?
Glucose is a product of photosynthesis:Carbon dioxide + Water = Glucose + OxygenThe carbon dioxide travels through the stoma at the bottom of the leaf.The water comes through the rootsThe light energy, which the chloroplast creates turns the carbon dioxide and the water into glucose, which the plant keeps for energy and then releases the oxygen for humans to breathe in.
How does glycolysis contribute to cellular respiration?
Glycolysis is the first stage in cellular respiration. It converts glucose into 2 pyruvate, which then moves into the Krebs Cycle. Glycolysis is anaerobic and takes place in the cytoplasm.
What determines if cellular respiration or fermentation will take place?
The Oxygen molecule determines if the Pyruvic acid enters Krebs cycle or undergoes fermentation. If Oxygen is present, it enters the Krebs cycle, whereas in its absence, it undergoes fermentation.
Facilitated diffusion moves large molecules through?
Transport proteins and carrier proteins
What moves through the lipid bilayer of a plasma membrane most rapidly K glucose an amino acid CO2 or starch?
co2
The cell uses energy to transport glucose through the cell membrane?
Glucose moves across the cell membrane through facilitated diffusion. This type of transport uses protein carriers to assist glucose molecules across the cell membrane from an area of high concentration to an area of low concentration.
What system moves glucose oxygen and carbon dioxide around the body?
Which organ system takes oxygen and glucose around the bodyhyfbhgh
The process where blood moves throughout the body?
As blood moves through the body, the concentration of oxygen decreases as the concentration of carbon dioxide increases in the body and the concentration of glucose in the blood also decreased. This is because body cells require glucose and oxygen for respiration/to produce energy, whilst carbon dioxide is a waste product of repiration thus the amount of carbon dioxide will increase. As it moves past/through the intestines, the concentration of glucose, lipids and ions increase as the small intestines reabsorbs food. As blood moves through the kidneys, the concentration of urea drops significantly however the concentration of dissolved ions may differ depending on what the body needs to retain. As blood moves through the liver, amino acids -> ammonia -> urea.And as it enters the left side of the heart, it has low concentration of oxyden and high concentration of carbon dioxide. As it moves out from the left side of the heart, it is oxygenated and has less concentration of carbon dioxide.

What sugar moves across the cell membrane by facitated difusion?
Glucose
What happens to glucose as it moves from consumer to consumer?
people die get over it!
How does the body regulate blood glucose levels?
Regulation of blood glucose is handled by the body's production of insulin. Insulin moves the glucose that is produced during digestion out of the bloodstream and into cells.
What organell is the site of glucose into ATP?
The mitochondrion.The first part of aerobic cellular respiration, glycolysis, which is anaerobic, takes place in the cytoplasm, which splits the glucose molecule into two 3-carbon pyruvic acid (pyruvate) molecules with a net gain of 2 ATP. The pyruvic acid moves into a mitochondrion, where the Citric Acid cycle (Krebs cycle) and electron transport chain produce another 28 or 30 ATP molecules.
