What stage does photosynthesis undergo to produce sugar?

The stages of photosynthesis

Light-dependent reactions Thylakoid membrane Light energy is captured by chloroplasts and stored as ATP
Calvin cycle Stroma ATP is used to create sugars that the plant will use to grow and live

How is glucose produced in plants?

Plants, unlike animals, can make their own food. They do this using a process called photosynthesis . During photosynthesis, plants produce glucose from simple inorganic molecules – carbon dioxide and water – using light energy.

Can plants use the sugar they produce during photosynthesis to directly power the work of the cell?

Yes! What do plants do with the extra glucose that they produce? They use it to produce carbohydrates , proteins, and fats. These are used as sources of stored energy.

How does sugar get metabolized?

Sugar Metabolism: From Food to Fuel

When you eat foods, enzymes in the digestive process break down proteins, fats, and carbohydrates into amino acids, fatty acids, and simple sugars. These byproducts are absorbed into your blood, where they are available to be used as energy when your body needs it.

How is photosynthesis metabolism?

Photosynthesis is a two-part metabolic process. The two parts of the biochemical pathway of photosynthesis are the energy-fixing reaction and the carbon-fixing reaction. … Both molecules contain energy and are used in the carbon-fixing reaction to form glucose.

Where is glucose metabolized?

In the liver, muscles, and the kidney, this process occurs to provide glucose when necessary. A single glucose molecule is cleaved from a branch of glycogen, and is transformed into glucose-1-phosphate during this process.

How plants store the products of photosynthesis?

Photosynthesis is the process plants and some algae use to convert light energy to chemical energy stored as sugar within chloroplasts — the energy factories found in plant cells. … Chloroplasts are full of chlorophyll, a green pigment key to photosynthesis, which helps the plant absorb light.

How do plants produce oxygen during photosynthesis?

During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. … This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

What are the substances needed for photosynthesis what substances are produced during photosynthesis?

The substances used during photosynthesis are carbon dioxide and water. The substances produced are glucose and oxygen gas.

Where is glucose produced in photosynthesis?

Glucose is the basic sugar produced during photosynthesis in stroma part of chloropast.

What sugars do plants produce?

All green plants produce sugars through photosynthesis, a natural process that turns sunlight into energy. These include glucose and fructose, which are converted by the plant into sucrose. Sucrose, glucose, and fructose are found naturally in all plants, and are the basis for all food energy.

What three things are used to make glucose in photosynthesis?

Rather, plants use sunlight, water, and the gases in the air to make glucose, which is a form of sugar that plants need to survive. This process is called photosynthesis and is performed by all plants, algae, and even some microorganisms.

How does a green leaf manufactures glucose from carbon dioxide and water?

Green plants manufacture glucose through a process that requires light, known as photosynthesis. This process takes place in the leaf chloroplasts. Carbon dioxide and water molecules enter a sequence of chemical reactions within the chloroplasts. … Glucose is a simple sugar with the molecular formula C6H12O6.

Which step of the reaction produces sugar?

the Calvin cycle
Stage II is called the Calvin cycle. This stage combines carbon from carbon dioxide in the air and uses the chemical energy in ATP and NADPH to make glucose.Feb 23, 2012

What are the 5 stages of photosynthesis?

Terms in this set (7)

  • Step 1-Light Dependent. CO2 and H2O enter the leaf.
  • Step 2- Light Dependent. Light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2.
  • Step 3- Light Dependent. The electrons move down to enzymes.
  • Step 4-Light Dependent. …
  • Step 5-Light independent. …
  • Step 6-Light independent. …
  • calvin cycle.

How are the simple sugars that are produced by photosynthesis stored as wood during tree growth?

It is stored as starch in the network of living cell contents called the symplast. Starch is a chain of sugars linked together. Starch is considered the money, or the energy, in the tree bank. The bank is the living xylem or wood in branches, stems, trunk, and roots.

What is the process of photosynthesis step by step?

What type of carbohydrate is created by photosynthesis?


Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants (Figure 5.5). After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose.

What is the product of photosynthesis?


Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product.

What are two ways that plants use the carbohydrates produced in photosynthesis?

– Organisms use carbohydrates produced by photosynthesis by oxidizing them to produce energy for respiration. – The glucose produced in green plants is directly utilized for respiration and other activities, while the excess is stored in the form of starch.

What is produced by plants during photosynthesis quizlet?

During photosynthesis, cells use carbon dioxide (Co2) and energy from the Sun to create sugar molecules and oxygen. Organelles that are found in plant cells and eukaryotic algae that conduct photosynthesis.

How does the plant use the products of photosynthesis quizlet?

Plant cells use water, carbon dioxide, and energy from sunlight to make glucose and oxygen. … The products of photosynthesis (oxygen and sugar) are reactants of cellular respiration.

How fast does sugar metabolize?

Usually, blood sugar starts to rise 10-15 minutes after a meal and reaches its peak after an hour.

Do all sugars metabolize the same?

The human body does not differentiate between naturally occurring sugars and those that are added to foods. The metabolism of all carbohydrates follows the same pathway, yielding the core monosaccharides as the end result. However, this does not necessarily make a cupcake and an apple nutritionally the same.

What does sugar metabolism do?

Sugar metabolism is the process by which energy contained in the foods that we eat is made available as fuel for the body. The body’s cells can use glucose directly for energy, and most cells can also use fatty acids for energy.

How do plants metabolize energy?

Metabolism is the set of life-sustaining chemical processes that enables organisms transform the chemical energy stored in molecules into energy that can be used for cellular processes. … Plants convert light energy from the sun into chemical energy stored in molecules during the process of photosynthesis.
