711 gas
Yeast produces the most gas for fermentation at around 75-85°F (24-29°C). Temperatures outside this range can slow down or inhibit yeast activity.
Cellular Respiration produces the most ATP, out of Cellular respiration, Photosynthesis, lactic acid Fermentation, and alcohol fermentation.
why is it reasonable that, of the three sugars, glucose would result in the most activiity suring the fermentation experiment
When oxygen is absent, most of the ATP produced in cellular respiration comes from anaerobic processes, primarily fermentation. In humans, this results in lactic acid fermentation, while in yeast, alcoholic fermentation occurs. Both processes regenerate NAD+ to allow glycolysis to continue, which produces a small amount of ATP. Overall, the yield of ATP in anaerobic conditions is significantly lower than in aerobic respiration.
Yes, the amount of yeast used can affect the amount of foam produced during fermentation. More yeast can lead to increased foam production, especially during the early stages of fermentation when yeast is most active. However, excessive foam can also lead to overflow, so it's important to use the right amount of yeast for the recipe.
sugar helps the most

Yeast is the microorganism that is responsible for fermentation in beer. Yeast metabolises the sugars extracted from grains, which produces alcohol and carbon dioxide, and thereby turns wortinto beer. In addition to fermenting the beer, yeast influences the character and flavour.[23] The dominant types of yeast used to make beer are Saccharomyces cerevisiae, known as ale yeast, and Saccharomyces uvarum, known as lager yeast; their use distinguishes ale and lager.[24] Brettanomycesferments lambics,[25] and Torulaspora delbrueckii ferments Bavarian weissbier.[26]Before the role of yeast in fermentation was understood, fermentation involved wild or airborne yeasts. A few styles such as lambics rely on this method today, but most modern fermentation adds pure yeast cultures
Yeast, most commonly Saccharomyces cerevisiae, is used in baking as a leavening agent, where it converts the fermentable sugars present in the dough into carbon dioxide. This causes the dough to expand or rise as the carbon dioxide forms pockets or bubbles. Brewer's yeast (also known as brewing yeast) can mean any live yeast used in brewing. It can also mean yeast obtained as a by-product of brewing, dried and killed, and used as a dietary supplement for its B vitamin content.
Alcoholic fermentation occurs most commonly in yeast and some bacteria. Yeast uses this process to produce alcohol and carbon dioxide during the breakdown of sugars.
Any yeast will ferment over time so it depends what you are doing with it... I think that the most productive and best suited would be Brewer's Yeast.

Temperature affects yeast respiration and fermentation because it influences the rate of enzyme activity. Yeast activity increases with higher temperature, up to a certain point, beyond which it decreases due to denaturation of enzymes. Optimal temperature ranges between 25-30°C for most yeast strains.
Carbon dioxide and alchohol:)
A stuck fermentation is where fermentation has stopped before all the sugar has been consumed. Yeast are organisms, and like most organisms they have an expected lifespan and they have nutritional requirements. You generally add less yeast to a fermentation than is required to complete the task on its own. Before fermentation starts the yeast rapidly reproduces itself so you end up with a much larger yeast colony. If what you are trying to ferment does not contain enough nutrition (i.e. oxygen, nitrogen, vitamins, sterols, UFAs) you will get a small, weak yeast colony that will all be dead before the sugar is completely consumed. Another factor is temperature. Most yeast has a quoted alcohol tolerance, but this is temperature dependant. Although fermentation speeds up as temperature increases, so does yeast mortality, and alcohol tolerance decreases.
It really depends on which fermentation you are referring to. The most common substrate is glucose, which is metabolized into either ethanol, lactic acid, or etc. along with carbon dioxide or hydrogen.
