Question
Chapter 7, Problem 3Q
Summary Introduction
To determine:
An evidence to prove or disprove the statement: “The evolution of aerobic respiration was driven by the success of photosynthetic microbes.”
Concept introduction:
Aerobic respiration requires the presence of oxygen. Oxygen is required to carry the electrons from one molecule to another molecule. Respiration is required for the generation of energy by breaking the carbohydrates and other noncarbohydrate compounds in the absence of carbohydrates.

able to undergo aerobic cellular respiration.
Explain the following observation. When a photosynthetic system is exposed to a brief flash of light, no oxygen is evolved. Only after several bursts of light is oxygen evolved.
Identifying carboxysomes in a bacterium suggests that this bacterium is using the Calvin cycle to convert the concentrated CO2 into biomass.
