Lactate formed in muscles can be utilised through _______________.

Why is lactate produced during strenuous exercise? A. Laktaat maak die bloed suur (asidose) wat ensiem funksie bevorderLactate makes the blood acidic (acidosis) which promote enzyme function. B. Rooibloedselle werk harder tydens oefening en produseer dus meer laktaat.Red blood cells work harder during exercise and thus produce more lactate. C. Om die NADH wat ophoop, om te skakel na NAD sodat glikolise bly funksioneer.To convert the accumulating NADH to NAD so that glycolysis keeps functioning. D. Dis 'n produk van lipied katabolisme.It is a product of lipid catabolism.

lactic acid is produced whenever muscle tissue contracts. Muscle tissue can contract in the absence of oxygen and lactic acid accumulates until fatigue sets in. On return to Aerobic conditions, the muscle tissue can contract again and the lactic acid is metabolised. Which of the following is the best interpretation of these observations?: A= formation of lactic acid is oxygen dependent, B= in anaerobic conditions, lactic acid is produced faster then it can be removed,C= lactic acid is produced only in anaerobic conditions,D= muscle contraction is independent of oxygen availability.

During strenuous exerciseGroup of answer choicesan oxygen debt can occur.lactic acid can be created in the muscle.almost all the contractions are tonic contractions.an oxygen debt can occur and lactic acid can be created in the muscle.

In human skeletal muscle, during anaerobic exercise the pyruvate formed from glycolysis is converted to lactate. Why is this reaction important?Question 4

What causes blood lactate to increase at higher intensities of exercise?Question 5Select one:a.The phosphagen system has a high flux producing more lactateb.Greater type II muscle fiber recruitmentc.The heart does not use lactate as a substrate for ATP synthesis at high intensitiesd.Hepatic glucose output can no longer buffer lactate
