9. Glucose is not readily available in the diets of most heterotrophs. So, how do organisms combat this to still go through glycolysis for energy? Organisms, like humans, will obtain most of their daily calories from food in the
forms of carbohydrates, fats, and proteins. The catabolism of these molecules will allow for their monomers to
enter glycolysis and the citric acid cycle. What happens in the absence of food? Starvation leads to significant
weight loss. In fact, people can lose up to 10 pounds per week with no food consumption. This dramatic and life
threatening weight loss stems from the fact that these people are unable to receive the nutrients they need from
food to go through glycolysis and the subsequent steps of cellular respiration. a) Identify the macromolecule being
catabolized to power cellular respiration when a person is starving. b) Identify the monomers of the macromolecule
identified in part (a). Connect your answer from part (a) to justify how this leads to dramatic weight loss in people
who are starving

You decide that the introduction should also discuss the extremophiles that are referred to as the archaea. these single-cell organisms are considered "extremophiles" due to their ability to survive and reproduce in environmental conditions that would be hostile for most living organisms. archaea species have been isolated from highly acidic sulfur springs, ocean floor thermal vents with temperatures that exceed boiling, and subarctic ice well below freezing. while still considered to be prokaryotic, the archaea have numerous differences that place them apart from the bacteria. choose the characteristics that separate the archaea from other prokaryotic cells. select all that apply. view available hint(s) select all that apply. archaea lack true peptidoglycan in their cell walls. the morphology of the cell is rigid and is geometric in shape, similar to a sphere or cylinder. the cytoplasmic membrane lipids of archaea have branched or ringform hydrocarbon chains. all currently identified and characterized archaea have been linked as the causative agent to an animal or human disease.
