1.why does cellular respiration in muscles that produces lactic acid supply less energy compared to aerobic respiration? 2.A 100-metre sprinter usually holds his breath while running compared with a long-distance runner. after running, tje sprinter needs seven litres of oxygen to remove the lactic acid in his muscle, EXPLAIN THIS DIFFERENCE BETWEEN THE SPRINTER AND THE LONG-DISTANCE RUNNER

*please help me*

Acceleration is a direct result of a.) balanced forces b.) unbalanced forces c.) gravity d.) velocity

During the day, plants produce by splitting water molecules in the light-dependent reactions of photosynthesis. at the same time, plants use cellular respiration to produce some of the needed by the light-independent reactions to make sugars. during the night, plants produce because takes place.

Asolution of an enzyme and a substrate was placed in a water bath and the temperature of the reaction was raised gradually. the graph shown was plotted at the end of the experiment. what can be concluded from the graph? a) temperature has no effect on the activity of the enzyme. b) the effect of temperature on the enzyme is unpredictable. c) the enzyme shows increased activity up to a certain temperature. d) the activity of the enzyme is inversely proportional to the temperature.
