Answer:
look
Explanation:
Flatworms, roundworms, and segmented worms are all invertebrates. Some species of each type of worm are free-living, meaning they are not dependent on another organism.Some are parasitic.
Flatworms belong to phylum Platyhelminthes. They do not have a coelom, respiratory system or a circulatory system.Tapeworms flukes are examples of flatworms.
Roundworms are part of the phylum Nematoda. They are bilaterally symmetrical invertebrates.They have a psuedocoelom. Ascaris lumbricodes is the most common human parasite.
Segmented worms are the most complex animals of these three invertebrates. They are placed in Annelida. Segmented worms have a true coelom, a circulatory system and a digestive system.An earthworm is a segmented worm.
A runner HAS to use the anaerobic respiration process,first we need to know the difference between anaerobic respiration and aeorobic respiration
<span>Anaerobic respiration is done by burning glucose directly without the presence of oxygen giving out lactic acid and energy </span>
<span>Aerobic respiration is done by burning glucose and oxygen giving out water + engergy + Co2 </span>
<span>1.) Take a stop-watch </span>
<span>2.) Take TWO or more runners </span>
<span>3.) Unlike Olympic race match ask ONE of the runners to run their fastes and the others to GRADUALLY speed up </span>
<span>4.) make the runners breath hard for air </span>
<span>5.) after finish line </span>
<span>6.) do a test of Lactic through urin test or use Lactometer (don't ask me how to use it 'cause I don't know lol) </span>
<span>7.) check the concerntration </span>
<span>8.) whoever has the LOWEST concerntration,take that runner time for running and meter to find speed you'll be able to spot out who has used aerobic respiration during the race</span>
Answer:Recall that the glycolytic pathway generates NADH in the cytosol in the oxidation of glyceraldehyde 3-phosphate, and NAD+ must be regenerated for glycolysis to continue. How is cytosolic NADH reoxidized under aerobic conditions? NADH cannot simply pass into mitochondria for oxidation by the respiratory chain, because the inner mitochondrial membrane is impermeable to NADH and NAD+. The solution is that electrons from NADH, rather than NADH itself, are carried across the mitochondrial membrane. One of several means of introducing electrons from NADH into the electron transport chain is the glycerol 3-phosphate shuttle (Figure 18.37). The first step in this shuttle is the transfer of a pair of electrons from NADH to dihydroxyacetone phosphate, a glycolytic intermediate, to form glycerol 3-phosphate.This reaction is catalyzed by a glycerol 3-phosphate dehydrogenase in the cytosol. Glycerol 3-phosphate is reoxidized to dihydroxyacetone phosphate on the outer surface of the inner mitochondrial membrane by a membrane-bound isozyme of glycerol 3-phosphate dehydrogenase. An electron pair from glycerol 3-phosphate is transferred to a FAD prosthetic group in this enzyme to form FADH2. This reaction also regenerates dihydroxyacetone phosphate.
