## Step 1: Understand the question. The question is asking about the process in which the sugars created by photosynthetic algae are eventually broken down.## Step 2: Analyze each option. ### Option A: Glycolysis, during respirationGlycolysis is the first step in the breakdown of glucose to extract energy for metabolism. It is a part of the cellular respiration process, which is how cells generate energy. This process occurs in the cytoplasm of the cell and does not require oxygen. ### Option B: The Calvin cycle, during photosynthesisThe Calvin cycle is a set of chemical reactions that take place in the chloroplasts during photosynthesis. It is not involved in the breakdown of sugars, but rather in the synthesis of sugars.### Option C: Electron transport chain during respirationThe electron transport chain is a series of complexes that transfer electrons from electron donors to electron acceptors via redox reactions, and couples this electron transfer with the transfer of protons across a membrane. This process is a part of cellular respiration, but it is not directly involved in the breakdown of sugars.### Option D: The Krebs cycle, during photosynthesisThe Krebs cycle, also known as the citric acid cycle or the tricarboxylic acid cycle, is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins. This process occurs in the mitochondria of the cell and requires oxygen. However, it is not involved in the breakdown of sugars created by photosynthetic algae.## Step 3: Based on the analysis, the correct answer is option A: Glycolysis, during respiration. This is the process where the sugars created by photosynthetic algae are eventually broken down.
