Keeping this in consideration, Which enzyme is found in yeast?
Fortunately, the yeast used in bread-making contains the enzyme maltase, which breaks maltose into glucose. When the yeast cell encounters a maltose molecule, it absorbs it.
Also, What is zymase made of?. Zymase. Zymase works on simple sugar that has been produced by the action of invertase and maltase.
Just so, What does the enzyme zymase do?
Zymase works on simple sugar that has been produced by the action of invertase and maltase. Zymase changes the simple sugar into alcohol and carbon dioxide gas, which causes dough to rise and expand (see Figure 9).
What is zymase in yeast?
: an enzyme or enzyme complex of yeast that promotes fermentation of sugar.
Those which produce carbon dioxide without the use of free “deamidizing” oxygen, such as zymase of yeast. Zymase is the active alcoholic fermentation enzyme of yeasts.
Yeast eats sucrose, but needs to break it down into glucose and fructose before it can get the food through its cell wall. To break the sucrose down, yeast produces an enzyme known as invertase.
This is simple sugar, such as glucose and fructose. Enzymes join monosaccharides together to form disaccharides (two monosaccharides) and polysaccharides (long chains of monosaccharides). Carbohydrase enzymes break disaccharides and polysaccharides into monosaccharides (simple sugars).
Zymase is an enzyme complex that catalyzes glycolysis, the fermentation of sugar into ethanol and carbon dioxide. As the conversion takes place, the reaction will gradually slow down. They occur naturally in yeasts.
If we want high enzyme activity, we need to control temperature, pH, and salt concentration within a range which encourages life. If we want to kill enzyme activity, extremes of pH, temperature and (to a lesser degree), salt concentrations are used to disinfect or sterilize equipment.
The enzymes most frequently used in bread-making are the α-amylases from different origins. Amylases and other starch-converting enzymes The industrial processing of starch is usually started by α-amylases (α-1,4-glucanohydro‐ lase).
Proteases are used by biscuit manufacturers to lower the protein level of flour. Trypsin is used to predigest baby foods.
While amylases are found naturally in yeast cells, it takes time for the yeast to produce enough of these enzymes to break down significant quantities of starch in the bread.

As fungi, yeasts are eukaryotic organisms. They typically are about 0.075 mm (0.003 inch) in diameter and have many forms, from spherical to egg-shaped to filamentous. Most yeasts reproduce asexually by budding: a small bump protrudes from a parent cell, enlarges, matures, and detaches.
The yeast is able to feed off the sugars and convert them into carbon dioxide, and small amounts of alcohol. ... Accordingly I would say, yeast generating carbon dioxide is a chemical reaction. The rising of the bread is a physical change caused by gas expansion.
In 1833, diastase (a mixture of amylases) was the first enzyme to be discovered,2 quickly followed by other hydrolytic enzymes such as pepsin and invertase,3 but the term enzyme was only coined in 1877 by Wilhelm Kühne.
To protect itself, the body makes catalase, the enzyme that decomposes hydrogen peroxide before it can form hydroxyl radicals.
Yeast produces the enzyme maltase to break moltose into glucose molecules that it can ferment. Once the starch has been broken down into these simple sugars, other enzymes in yeast act upon simple sugars to produce alcohol and carbon dioxide in the bread making step called fermentation.
The full list of enzymes includes amylase, alpha-galactosidase, glucoamylase, cellulase, protease, maltase, lactase, invertase, lipase, pectinase with phytase, hemicellulose, and xylanase.
The majority of enzymes are proteins made up of amino acids, the basic building blocks within the body. There are exceptions with some kinds of RNA molecules called ribozymes.  Amino acid molecules are connected through linkages known as peptide bonds that form proteins.
Enzymes are biological catalysts composed of amino acids; that is, they are proteins.
We hypothesize that sucrose and/or glucose will create a higher CO2 concentration over time in yeast fermentation because they have a simple chemical structure, making them easy to break down. Lactose is not as easily broken down in yeast fermentation due to yeast lacking the enzyme lactase which breaks lactose down.
When active (live) yeast has both sugar and oxygen available to it, it 'breathes' by a process called aerobic respiration. In this reaction, yeast cells use glucose (sugar) and oxygen (from the air) to produce energy. They also produce water and carbon dioxide (a gas). This is the same chemical process used by humans.
Zymase converts glucose into ethanol through the process of fermentation. It is found naturally in the yeasts and its activity is highly dependent on the type of yeast strains.
