In your own words, explain how a single molecule of glucose is converted into ~30 or more molecules of ATP in cellular respiration
Answers
Answer: Throughout the stages of cellular respiration
Explanation:
Fair warning I'm only a college freshman so you may be able to find more detailed answers than what I'm about to give you.
During cellular respiration there are a number of processes that must be taken into account when dealing with a glucose molecule.
Glycolysis: The molecule of glucose is a 6-carbon molecule, in this process that takes place in the cytoplasm of the cell, it is split into two 3-carbon molecules, these are pyruvates, during this, 2 ATP is made as a byproduct(along with 2 NADH molecules but I'll just focus on the ATP moving forward).
Transformation of pyruvate: For eukaryotic cells, the pyruvate molecules from Glycolysis are transferred into the mitochondria, which of course are sites for cellular respiration. With Oxygen available, aerobic respiration would continue but if not, fermentation would take place which would drastically reduce total ATP reduction throughout one cycle. The pyruvates are transformed into a 2-carbon acetyl group which is then oxidized and now compatible for Coenzyme A to pick up, which results in the compound Acetyl Coenzyme A. This process ends up producing 1 NADH molecule from the reduction of NAD+ due to the 2 carbon molecule being oxidized.
Citric Acid Cycle: This stage begins as soon as Acetyl CoA combines with a 4-carbon molecule called Oxaloacetate which ends up forming citric acid, that has 6-carbon atoms. Long story short the citric acid goes through a great number of reactions that produces a total of 2 ATP molecules.
Oxidative Phosphorylation: This stage of aerobic respiration consists of the electron transport chain and chemiosmosis process. The energy of NADH and FADH2 molecules that were produced in the Citric Acid Cycle is what's used to create the final majority of ATP molecules within this whole process. 1. Throughout the electron transport chain, excited electrons move along its network in the inner membrane of the mitochondria. As it moves, molecules it passes by uses the electrons energy to pump Hydrogen ions/protons from the inner membrane towards the intermembrane space. This transfer of ions creates an electrochemical gradient which is necessary for the synthesis of ATP in the following process, Chemiosmosis. The Electron Transport Chain produces about 2-3 ATP. 2. In Chemiosmosis, the newly formed electrochemical gradient causes the gathered Hydrogen ions to flow from the intermembrane space into the matrix, therefore lowering the its concentration(search up a image of this if you need to). This flow is thanks to and mediated by ATP synthase. Finally ATP synthase accepts 3-4 Hydrogen ions so an inorganic phosphate group can react with an ADP (Adenosine diphosphate) compound to produce one ATP molecule. In total, 24-28 molecules of ATP is formed.
This is how a single molecule of glucose can produce more than 30 molecules of ATP in aerobic cellular respiration. Fermentation on the other hand, would most likely produce half of which aerobic respiration would produce.

DNA is the hereditary material in humans and almost all other organisms. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA). DNA contains the code for building and maintaining an organism.
Answer:
The structure that is responsible for the governance of a cell is the DNA, which is located in the nucleus of the cell.
Explanation:
DNA: It is the genetic material containing genetic information.It is present in the chromosomes inside the nucleus. The genetic information of DNA is stored as code in the four nucleobases namely Adenine, Guanine, Cytosine, and Thymine. The most unique feature of the DNA is that it is self-replicated and makes similar copies of itself. DNA is a double helical structure found in all living organisms including some viruses.In Eukaryotes along with the nucleus, DNA is also present in Mitochondria and Chloroplasts.For more information:

Answers
The correct order of glycolysis reactions is:
Two phosphate groups from two ATP molecules are joined to glucose.Two NADP molecules are converted into two NADH molecules.A six-carbon molecule is broken down into two three-carbon molecules.Two three-carbon molecules are converted into two molecules of pyruvate as four molecules of ATP are produced.During glycolysis, the glucose molecule is converted to Glucose-6-phosphate as a result of phosphorylation. The phosphate group from ATP is joined to the glucose molecule by an enzyme known as hexokinase.
The glucose-6-phosphate then undergoes isomerization to become fructose-6-phosphate which is then phosphorylated again by the hexokinase enzyme to become fructose-1,6-biphosphate.
An aldolase enzyme converts fructose-1,6-biphosphate to one molecule of glyceraldehyde-3-phosphate and one molecule of dihydroxyacetone phosphate. The latter is then converted to another molecule of glyceraldehyde-3-phosphate.
A dehydrogenase enzyme converts glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate with NADH being generated from the reduction of NAD+.
A kinase enzyme then converts 1,3-bisphosphoglycerate to 3-phosphoglycerate with ATP being generated from ADP. A mutase enzyme quickly converts the 3-phosphoglycerate to 2-phosphoglycerate while an enolase enzyme converts the latter to phosphoenolpyruvate.
Finally, a pyruvate kinase enzyme converts phosphoenolpyruvate to pyruvate with another ATP being generated.

Answers
Objects are brought into focus on the retina by changes in the curvature and thickness of the lens.
What is eye lens?The lens basically directs light rays onto the retina. The lens is clear and replaceable if necessary. As we age, our lenses deteriorate, necessitating the use of reading glasses.
The lens is normally clear and is located behind the iris. The pupil directs light to the lens.
Small muscles attached to the lens can cause the lens to change shape, allowing the eyes to focus on objects that are close or far away.
Light bends (refracts) and focuses on the retina at the back of the eye as it passes through the lens.
The lens's thickness and curvature can be adjusted to focus on objects at various distances and ensure that the image is as clear as possible (this process is known as accommodation).
Thus, eye lens helps to focus the object.
