Though vertebrates are aerobes, but their `ul((i))` show anaerobic respiration during `ul((iii))`. During this `ul((iii))` of skeletal muscle fibres is broken down to release lactic acid and energy. Lactic acid, if accumulates causes muscle fatigue. Fill up the blanks in the above paragraph and select the correct option.

Assertion : Anaerobic respiration sometimes occurs in our skeletal muscles during strenous exercise. Reason : Pyruvic acid is reduced to lactic acid by lactate dehydrogenase in the absence of oxygen.

Assertion : Anaerobic respiration sometimes occurs in our skeletal muscles during strenous exercise. Reason : Pyruvic acid is reduced to lactic acid by lactate dehydrogenase in the absence of oxygen.

The characteristic processes observed in anaerobic respiration are : (I) presence of oxygen (II) release of carbon dioxide (III) release of energy (IV) release of lactic acid

Red muscle fibres I. perform slow and sustained contractions for long periods without fatigue. II. Depend mainly on anaerobic glycolysis. III. Carry out aerobic contraction without accumulating much lactic acid IV. Perform faster contraction rate. Choose the correct option.

Consider the following statements (i) - (iii), each with two blanks (i) Pseudostratified epithelium lines the ul(1) tract while transitional epithelium lines the ul(2) tract (ii) Lacunae of bones house ul(3) while lacunae of cartilage contain ul(4) (iii) Tendon contain bundles of ul(5) fibres and rows of ul(6) cells between the them Which one of the following options, gives the correct fill ups for the respective blank numbers from (1) to (6) in the statements ?

Read the following statements is context to muscle tissue and choose the correct answer . (i) Excessive exercise results in anaerobic Respiration and forms lactic acid . (ii) As per sliding filament theory of muscle contraction, the filament that moves to shorten a muscule is actin . (iii) The muscles primarily involved in locomotion is striated muscles .
