What is the relationship between photosynthesis and cell respiration? Be sure to include the overall chemical equation for both reactions correct answer: The relationship between cell respiration and photosynthesis is an inverse relationship, that both sides are opposite each other. In photosynthesis, CO2 is taken in, and O2 is excreted, while in cellular respiration, C02 in excreted, and O2 is needed for the reaction to commence. Distinguish between oxidation and reduction. Why are these p...

A dynamic steady state results when A. a molecule stops being degraded. B. an organism is at equilibrium with its surroundings. C. there is no net energy transfer. D. the rate of intake or synthesis of a molecule equals the rate of its disappearance - Choice D is correct. A dynamic steady state results when the rate of synthesis or intake of a molecule equals the rate of its breakdown, consumption, or conversion into some other product. For example, a dynamic steady state in the blood ma...
