Sierra is asked to demonstrate how carbon travels from the atmosphere to living organisms, then back to the atmosphere. She draws a diagram showing carbon dioxide from the atmosphere being taken in by a plant. An animal then consumes the carbon dioxide in the plant, uses it as a source of energy, then exhales, returning the carbon dioxide to the atmosphere. Which of the following statements indicates a correction that needs to be made on Sierra's diagram?

An animal then consumes the carbon dioxide in the plant, uses it as a source of energy, then exhales, returning the carbon dioxide to the atmosphere.

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
