Question

the diagram below illustrates an experiment setup by high school students. yeast, sugar, and warm water are placed in a flask, and then the flask is sealed with a limp balloon. over time, the flask gets warm and the balloon starts to fill. what process is the experiment most likely designed to show? (1 point) anaerobic respiration homeostasis protein synthesis photosynthesis

Explanation:

Yeast is a microorganism that can perform anaerobic respiration (fermentation) in the absence of oxygen. In this experiment, yeast uses sugar as a substrate. During anaerobic respiration, yeast breaks down sugar and produces carbon dioxide gas (which fills the balloon) and ethanol. The flask getting warm indicates that energy (in the form of heat) is released during the process, which is consistent with the energy - releasing nature of respiration. Homeostasis is the maintenance of a stable internal environment in an organism. Protein synthesis is the process of making proteins from amino acids, which is not related to the gas production and heat release shown here. Photosynthesis is a process carried out by plants (and some other organisms) that uses light energy to convert carbon dioxide and water into glucose and oxygen, which is not relevant as there is no light source mentioned and yeast does not perform photosynthesis.

Answer:

anaerobic respiration
