a student runs 5 kilometers (km) each afternoon at a slow, leisurely pace. one day, she runs 2 km as fast as she can. afterward, she is winded. the next morning, she wakes up very sore. she thought she was in great shape - why was she winded? what has accumulated in her muscles? identify the name of this type of cellular respiration.

The correct answer is that our student accumulated lactic acid.

Explanation:

What is acid lactic and where it comes from? It comes from the breakdown of glucose when there is no oxygen present (glycolytic metabolism), that is, in an anaerobic exercise such as running or cycling at high speed, like the case of our student, where there is a high intensity and a very short duration.

What happen then?  When we keep doing exercise with high intensity an exercise, lactic acid will begin to accumulate by not giving the body time to remove it.

How can we avoid lactic acid? With training, there is no more. Based on training, the body deploys adaptive mechanism that causes lactic acid not to accumulate so quickly and if it begins to do so, the muscle supports it more effectively.

glycolysis is a process that fuel your metabolism. it is apart of cellular respiration the process that produce atp.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
