What happens to all of the 6 carbons that were in your glucose molecule?

The 6 carbon and oxygen from the glucose are slowly removed thought the process of glycolysis, oxidation of pyruvate acid, and Krebs cycle in the form of carbon dioxide. Water is not made until the electron transport chain.

Can we use molecules other than glucose in cellular respiration?

Question: Cells can use organic molecules other than glucose in the process of cellular respiration, but the substrates enter the pathway at later points. When fats are used as an energy source the fat must first be broken down into glycerol and fatty acids.

Why glucose is more preferred by cells for respiration than other carbohydrates?

Energy Production Many cells prefer glucose as a source of energy versus other compounds like fatty acids. Sunlight energy was required to produce these high-energy bonds in the process of photosynthesis. Cells in our bodies break these bonds and capture the energy to perform cellular respiration.

Can molecules other than glucose be used to make ATP?

Sugars other than glucose are similarly converted to pyruvate after their conversion to one of the sugar intermediates in this glycolytic pathway. During pyruvate formation, two types of activated carrier molecules are produced—ATP and NADH. The pyruvate then passes from the cytosol into mitochondria.

Where do all the carbons of glucose end up?

Glucose has six carbon atoms. 2. The carbon atoms from glucose end up in pyruvate molecules as a product of glycolysis. Se 1 U Glycolysis and the Krebs Cycle 77 Page 9 21 3.

What happens to the carbons in glucose as they pass through cellular respiration?

The carbons from glucose end up in ATP molecules at the end of cellular respiration. Energy is stored within the chemical bonds within the glucose molecule.

How are molecules other than glucose used as energy sources?

Some molecules enter at glycolysis, while others enter at the citric acid cycle. This means that all of the catabolic pathways for carbohydrates, proteins, and lipids eventually connect into glycolysis and the citric acid cycle pathways.

Why is glucose better than fructose for cellular respiration?

Glucose’s rate of energy production was more than three times that of fructose. Glucose was directly used in the glycolysis cycle and did not require any extra energy to convert it into a usable form (Freeman, 154). This supported why glucose was the most efficient.

WHY CAN T cells use glucose directly for energy?

Linking the oxidation of glucose to all of the functions that require energy would be inefficient: the cell might lose energy produced by the oxidizing glucose if all of the energy wasn’t needed immediately. ATP does not have to be used immediately.

How many carbons are in citrate?

six carbon atoms
Acetyl-CoA then combines with one oxaloacetate molecule, a four-carbon molecule, to produce a molecule of citrate, which contains six carbon atoms, and is the starting material for the citric acid cycle.

When glucose a 6 carbon sugar is broken down during glycolysis What product forms?

pyruvate molecules
Glycolysis is the splitting, or lysis of glucose. Glycolysis converts the 6-carbon glucose into two 3-carbon pyruvate molecules. This process occurs in the cytoplasm of the cell, and it occurs in the presence or absence of oxygen. During glycolysis a small amount of NADH is made as are four ATP.

Why do we need ATP why not just release energy from glucose directly?

It is much more energy efficient to add and remove those phosphate groups than to add and subtract elements from a glucose molecule, as there is no way to effectively break it down without significantly changing its structure, which makes it harder to build back up.

What is the role of ATP in carbohydrate respiration?

As a result of carbohydrate respiration, your cells produce large quantities of ATP, which the cells then use for a variety of things. Explains Dr. Lauralee Sherwood in her book “Human Physiology,” one of the uses of ATP in the body is in muscle contraction 3.

How many ATP and NADPH are needed to make 1 glucose?

Work out how many ATP and NADPH molecules will be required to make one molecule of glucose through the Calvin pathway. Calvin cycle can be described under three stages: carboxylation, reduction and regeneration. For every CO2 molecule entering the Calvin cycle, 3 molecules of ATP and 2 of NADPH are required.

What is the difference between ATP and glucose?

Although it carries less energy than glucose, its structure is more complex. The “A” in ATP refers to the majority of the molecule, adenosine, a combination of a nitrogenous base and a five-carbon sugar. The “TP” indicates the three phosphates, linked by bonds which hold the energy actually used by cells.

Why does it take 6 O2 molecules of oxygen to make ATP?

To metabolize a single glucose into usable ATP, it requires 6 O2 molecules! So what is the reason? Because it takes about 1/2 an oxygen to oxidize the NADH and FADH2 that is produced in the glycolysis and Kreb’s Cycle portions of respiration, respectively.
