Energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. It states that matter can be neither created nor destroyed in ordinary chemical or physical changes.
Answer:
Explanation:
The rate limiting reaction of aerobic respiration involves the phosphorylation of fructose phosphate by the enzyme phosphofructokinase. The rate at which this enzyme makes product is [increased, decreased] when ATP levels rise because the molecule ATP binds to an allosteric site on the enzyme and acts as a direct inhibitor. When ATP levels fall AMP binds to the allosteric site of phosphofructokinase. This interaction leads to an increase of cellular ATP, so that this is an example of a negative feedback loop.
True! because if you have more than one variable, you aren’t going to know which variable changed the dependent variable.
