Anaerobic respiration
A) occurs without oxygen and may produce methane gas or ethanol.
B) is a type of photosynthesis that does not require carbon dioxide.
C) typically results in major increases of biomass.
D) produces oxygen, which is used to break down glucose and other plant sugars.
Question 2
In the fall, Rose bought some fresh apple cider without preservatives sold by the local orchard. After several weeks stored in the refrigerator, the cider had carbonation. Rose also noticed the taste of alcohol in the cider.
Friends later told her that she had accidentally made hard cider. Rose wondered how this could happen, and then her friends explained. After some time, natural yeast in her cider A) broke down the glucose and made alcohol by fermentation.
B) produced glucose by the process of alcoholic fermentation.
C) broke glucose down into alcohol by aerobic respiration.
D) used photosynthesis to create alcohol and sugars.
ATP yield per molecule of glucose at each stage of cellular respiration.
