Where in a plant cell is oxygen used and carbon dioxide produced?


Where is glucose made in a plant cell?

Where is glucose located in a cell?

Glucose molecules are absorbed from intestinal cells into the bloodstream. The bloodstream then carries the glucose molecules throughout the body. Glucose enters each cell of the body and is used by the cell’s mitochondrion as fuel.

Where is glucose produced in a leaf?

leaf chloroplasts

How glucose is made in factory?

Glucose is formed by the hydrolysis of many carbohydrates, including sucrose, maltose, cellulose, starch, and glycogen. Fermentation of glucose by yeast produces ethyl alcohol and carbon dioxide.

What is the raw material of glucose?

Glucose, also known as dextrose, is a natural sweetener, which is obtained from starch containing plants such as corn, wheat, rice and cassava.

Does glucose dissolve in water?


What happens when you mix water and glucose?

Glucose dissolves in water because polar water molecules attach to the glucose molecules. When a glucose molecule (centre) is placed into water the negatively charged oxygen ions (red) attract and surround the positively charged O-H (hydroxyl- ) groups in glucose, forming hydrogen bonds (white).

What happens if glucose and water are mixed?

– Glucose is a polar molecule. – The water molecules will then surround each molecule of glucose and weaken the bonds holding it to the rest of the molecules of sugar. – After a while, the water molecules will isolate these glucose molecules and break their bonds with the rest of the sugar.

Why does glucose form ring structure in water?

These ring structures result from a chemical reaction between functional groups on opposite ends of the sugar’s flexible carbon chain, namely the carbonyl group and a relatively distant hydroxyl group. Glucose, for example, forms a six-membered ring (Figure 2).

How does glucose dissolve in water?

A Water-soluble sugar The reason glucose dissolves readily in water is because it has lots of polar hydroxyl groups which can hydrogen-bond with water molecules. Hydrogen bonds are very important intermolecular forces which determine the shape of molecules like DNA, proteins and cellulose.

Which form of glucose is most stable?

The most stable form of glucose (blood sugar) is a six-membered ring chair conformer with its five substituents all in equatorial positions.

Why glucose is called Glucopyranose?

Glucose is a six-carbon molecule with an aldehyde functional group, it is due to the intramolecular attraction between the hydroxyl groups on the carbons and the oxygen in the aldehyde functional group that these linear molecules cyclize into rings.

Is Glucopyranose same as glucose?

As nouns the difference between glucose and glucopyranose is that glucose is (carbohydrate) a simple monosaccharide (sugar) with a molecular formula of c6h12o6; it is a principle source of energy for cellular metabolism while glucopyranose is (carbohydrate) the pyranose form of glucose.

Is glucose a element?

Glucose is a compound not an element because, glucose is a molecule having the formula C6H12O6 which means it comprises of 6 carbon atoms, 12 hydrogen and 6 oxygen atoms.

What is glucose needed for?

Blood sugar, or glucose, is the main sugar found in blood. The body gets glucose from the food we eat. This sugar is an important source of energy and provides nutrients to the body’s organs, muscles and nervous system.

What is the source of oxygen atoms in glucose?

So O2 “released” in photosynthesis comes from water and not CO2 . Rather CO2 provides the carbon atom for glucose synthesis. And so does the oxygen atoms present in glucose finally come from CO2 while going through the Calvin cycle.

Is oxygen a mixture?

*Note: pure oxygen gas consists of molecules but it is still considered an element, rather than a compound, as the molecules are made up of a single type of element….Pure Substances.

Pure Substance Element or Compound? Consists of:
Ammonia (NH3) compound ammonia molecules

Is glucose a protein?

Between 50–60% of protein becomes glucose and enters the bloodstream about 3–4 hours after it’s eaten. Don’t eat fruit, fruit juice, or a “sweet” (often called fast-acting carbohydrates) for a snack without also eating protein. The protein will slow the absorption of carbohydrate.

Is glucose a carb or protein?

Carbohydrates, or carbs, are sugar molecules. Along with proteins and fats, carbohydrates are one of three main nutrients found in foods and drinks. Your body breaks down carbohydrates into glucose. Glucose, or blood sugar, is the main source of energy for your body’s cells, tissues, and organs.

What vegetables are high in glucose?
