74) Human muscle cells may produce lactic acid when they run out of oxygen.
74) Human muscle cells may produce lactic acid when they run out of oxygen.
Given that your cells undergo lactic acid fermentation when they don't have enough oxygen, why does muscle function decrease when there is less oxygen than the cells need? Explain
If your muscle cells used alcohol fermentation instead of lactic acid fermentation, which of the following might occur under low oxygen conditions? A) You would no longer be able to regenerate NAD+ B) You would no longer be able to produce ATP C) You would produce ethanol instead of lactic acid D) You would produce less CO2
Lactic acid is formed in our muscles when we are physically active and is responsible for muscle pain. An elemental analysis showed that this compound contains 40% mass of carbon (C), 6.71% mass of hydrogen (H) and 53.3% mass of oxygen (O). Determine the empirical formula and the molecular formula for lactic acid. (The molar mass of lactic acid is 90.08 g / mol) Please show all the steps and procidure.
During exercise when the body lacks an adequate supply of oxygen to support energy production, the pyruvate that is produced from the breakdown of glucose is converted into lactate. High lactate levels can lead to acidity in the muscle cells as some of the lactate hydrolyzes to lactic acid. The dissociation of lactic acid to lactate is shown in the reaction. Lactic acid has a p?a of 3.86. Lactic acid dissociates into the lactate ion and a hydrogen ion. The...
When oxygen is unavailable during heavy exercise, muscle cells use _____ to generate energy.

Describe the 3 primary ways that skeletal muscle cells use to regenerate (produce) ATP. For each, name and describe it, then state any advantages and disadvantages, defending your statements with facts or information that supports your statement. (hint: think in terms of speed of production, location of production within the cell, availability of specific substrates – name them, oxygen requirements, and wastes produced).
help A monoprotic weak acid, HA, dissociates in water according to the reaction HA(aq) = (aq) + A (aq) The equilibrium concentrations of the reactants and products are [HA] = 0.180 M, H+] = 3.00 x 10-4 M, and A) = 3.00 x 10-4 M. Calculate the value of pK, for the acid HA. pKg = During exercise when the body lacks an adequate supply of oxygen to support energy production, the pyruvate that is produced from the breakdown of...
Why are cells able to produce much more ATP per sugar molecule when oxygen rather than an organic molecule is used as the terminal receptor?
Trees are sometimes called the “lungs” of the planet. The oxygen they release comes from Select one: a. Photosystem 2 b. The Krebs cycle c. The Calvin cycle d. Photosystem 1 e. Pyruvate oxidation -- Which of the following best describes the process of fermentation? Select one: a. It allows the production of ATP in oxygen-rich environments b. It oxidizes NADH to NAD+ c. It leads to the production of lactic acid in yeast cells d. It allows glycolysis to...
