How and when are the different sources of muscle metabolism that you already know about—creatine phosphate (the phosphagen system), aerobic respiration, and anaerobic respiration (lactic acid system)—used during exercise? Why is heat produced during exercise? You may need to do further research.
Prepare a step-by-step summary of how the body is supplied with energy over the course of exercising. Keep in mind how ATP is supplied to the muscle cells over the first few seconds, minutes, and eventually the longer times of a workout.
Also, show the relationship between heat production and muscle use. You may use a variety of formats such as slide show, a podcast, a poster, a diagram, or a paragraph to present your summary.
CAN SOMEONE HELP ME WITH THIS QUESTIONS?? THANK YOU
If all organisms originated in their present forms during a single event, Darwin wondered, why was there a distinctive clustering of similar organisms in different regions of the world? Why were all types of organisms not randomly distributed?
Why would living and fossilized organisms that looked similar be found within the same region?
Why did the Galápagos species so closely resemble organisms on the adjacent South American coastline?
Why was there such a diversity of species in such a small area? Could these species have been
modified from an ancestral form that arrived on the Galápagos Islands shortly after the islands
were formed?
