This is a true statement. An electron closer to the nucleus would be difficult to remove because the electronegativity of the atom would be greater.
Glucose is consumed and carbon dioxide is produced during the combined processes of glycolysis and cellular respiration.
Glucose is a simple sugar. Glucose is the most common monosaccharide, a type of carbohydrate. Glucose is primarily produced by plants and most algae during photosynthesis from water and carbon dioxide with the help of sunlight, where it is used to produce cellulose in cell walls, the world's most abundant carbohydrate.
A glucose molecule is gradually broken down into carbon dioxide and water during cellular respiration. Some ATP is produced directly along the way in the reactions that transform glucose. However, much more ATP is produced later in the process known as oxidative phosphorylation. The movement of electrons through the electron transport chain, a series of proteins embedded in the inner membrane of the mitochondrion, drives oxidative phosphorylation.
During glycolysis, a six-carbon sugar, glucose, undergoes a series of chemical transformations. It eventually degrades into two molecules of pyruvate, a three-carbon organic molecule. ATP is produced in these reactions.

There is a valve at the meeting point between each ureter and the bladder prevents the back flow of urine from the urinary bladder to the kidney
Answer:
Similarity
Both nervous and endocrine system are similar in a way that they perform the regulatory function in the body and act as regulator in various body functions.
Difference
1. nervous system uses electrical impulses (neural)for signaling while endocrine system uses chemical signals called hormones, which travel through the bloodstream and control the actions of cells and organs.
2. The nervous system can respond quickly to stimuli, through the use of action potentials and neurotransmitters. Responses to nervous system stimulation are typically quick but short lived. The endocrine system responds to stimulation by secreting hormones into the circulatory system that travel to the target tissue.
