Question
Yeast were exposed to various sugars in culture without oxygen. According to the data, in the culture with which sugar would the most ATP be measured?
Responses
A maltose, because it is a disaccharide and has more high energy bondsmaltose, because it is a disaccharide and has more high energy bonds
B glucose, because it is a monosaccharide and is easily metabolized by yeastsglucose, because it is a monosaccharide and is easily metabolized by yeasts
C lactose, because yeasts have this sugar readily available in their growth medialactose, because yeasts have this sugar readily available in their growth media
D sucrose, because it is a disaccharide and is the most plentiful sugar for yeasts
B glucose, because it is a monosaccharide and is easily metabolized by yeasts
To determine in which sugar culture the most ATP would be measured, we need to consider the type of sugar and how easily it can be metabolized by yeast in the absence of oxygen.
Looking at the options provided:
A. Maltose is a disaccharide and has more high-energy bonds.
B. Glucose is a monosaccharide and is easily metabolized by yeast.
C. Lactose is readily available in the growth media of yeasts.
D. Sucrose is a disaccharide and is the most plentiful sugar for yeast.
Considering that glucose is a monosaccharide and is easily metabolized by yeast, option B is the most likely correct answer. Therefore, the most ATP would be measured in the culture with glucose.
To determine which sugar would result in the most ATP being measured in the yeast culture, we need to consider two factors: the type of sugar and its availability for yeast metabolism.
A. Maltose, because it is a disaccharide and has more high energy bonds.
Explanation: Maltose is a disaccharide composed of two glucose molecules. Disaccharides like maltose contain more high-energy bonds compared to monosaccharides. These high-energy bonds can be broken down by yeast through a process called glycolysis, producing ATP. However, the availability of maltose in the yeast growth media is not mentioned, so we cannot determine if it is the most plentiful sugar.
B. Glucose, because it is a monosaccharide and is easily metabolized by yeast.
Explanation: Glucose is a monosaccharide and the primary source of energy for yeast metabolism. Yeasts readily metabolize glucose through glycolysis, which generates ATP. Since glucose is easily metabolized and likely available in the yeast growth media, it is a strong candidate for producing the most ATP.
C. Lactose, because yeasts have this sugar readily available in their growth media.
Explanation: Lactose is a disaccharide composed of glucose and galactose. Yeasts typically do not have lactose readily available in their growth media. Therefore, even though lactose can potentially produce ATP when broken down, its availability in the yeast culture is not specified, making it less likely to result in the most measured ATP.
D. Sucrose, because it is a disaccharide and is the most plentiful sugar for yeasts.
Explanation: Sucrose is also a disaccharide composed of glucose and fructose. If it is mentioned that sucrose is the most plentiful sugar available in the yeast growth media, it is a strong contender for producing the most ATP. However, without information regarding the abundance of sucrose, we cannot conclusively determine its impact on ATP production.
Given the information provided, the most plausible answer would be:
B. Glucose, because it is a monosaccharide and is easily metabolized by yeast.
