How does equal and splenda affect yeast respiration?

Equal (Aspartame) and Splenda (sucralose) are artificial sweeteners that do not significantly contribute to yeast respiration because they are not fermentable sugars. Yeast primarily utilizes sugars like glucose for energy through fermentation, leading to carbon dioxide and ethanol production. Since Equal and Splenda do not provide the necessary energy substrates, they generally do not support yeast growth or respiration effectively. Consequently, their presence may not have a substantial impact on yeast metabolism compared to natural sugars.
