Assertion: Red muscles depend on anaerobic process for energy. Reason: Red muscles have few number of mitrochondira in themA. If both assertion and reason are ture and reason is the corect explanation of assertionB. If both assertion and reason are ture but reson is not the correct explanation of assertionC. If assertion is true reason is falseD. If both assertion and reason are false |
Answer» Correct Answer - d Muscle contains a red coloured oxygen storing pigment called myoglobin. Myoglobin content is high in some of the muscles which gives a reddish appearance to them. Such muscles are called the red fibres. These muscles also contain plenty of mitochonidria which can utilise the large amount of oxygen stored in them for ATP production. These muscles, therefore, can also be called aerobic muscle. |

Statement 1 is incorrect but statement 2 is correct.D. Both statement 1 and 2 are incorrect. |
Answer» Correct Answer - B Locomotion is voluntary movement by an organism from one place to another. It is difficult to separate movement from locomotion. The two are linked by stating that all locomotion are monements but all miovement are not locomotion. |

Assertion: A parson undergoes fatigue very soon during execies. Reason : Muscle fibres undergo oxygen debt during exercies.A. If both assertion and reason are ture and reason is the corect explanation of assertionB. If both assertion and reason are ture but reson is not the correct explanation of assertionC. If assertion is true reason is falseD. If both assertion and reason are false |
Answer» Correct Answer - b During strenous exercise, the muscle does not get sufficient oxygen to meet its energy requirement immediately. So, muscle contracts in the absence of oxygen. But it gets fatigued sooner in the absence of oxygen as the metabolic products of cellular respiration mainly lactic acid accumulates. The accumulation of lactic acid leads to muscle fatigue. After strenuous exercise, the oxygen consumption of muscle exceeds. The extra oxygen consumed during recovery is called debt of muscle. It is used in oxidizing the accumulated lactic acid aerobically and in restoring the depleted creatine phosphate and ATP in the muscle fibre. A small part of oxygen debt also goes to myoglobin which binds and stores oxygen for future use. |

Sarcoplasmic reticulum of muscle fibres is the store house ofA. CalciumB. SodiumC. ChlorideD. Potassium. |
Answer» Correct Answer - A | |
534. |
Assertion: on stimulation, a muscle cell releases calcium ions `(Ca^(2+))` from sarcoplasmic reticulum. Reason: By reacting with a protien complex, `Ca^(2+)` uncover active sites on the actin filaments.A. If both assertion and reason are ture and reason is the corect explanation of assertionB. If both assertion and reason are ture but reson is not the correct explanation of assertionC. If assertion is true reason is falseD. If both assertion and reason are false |
Answer» Correct Answer - b A neural signal on reaching the nerromuscular junction releases a neutrosmitter (acetylcholine) which generates an action potential in the sarcolemma. This spreads through the muscle fibre and causes the release of calcuim ions from sarcoplasmic reticulum into the sarcoplasm. Increase in `Ca^(2+)` level leads to the binding of calcium with a subunit of troponin on actin filaments and thereby removing the mask of active sites for myosin. |

In a muscle undergoes rapid contraction and relaxation, the sarcoplasmic reticulum extensionA. requires constant plugging in and out of `Ca^^(2+)`B. rapidly synthesise myosinC. does not require energy all of these.D. all of these |
Answer» Correct Answer - A Sacoplasmic reticulum of muscle cells store `Ca^(2+)` ions. During contracting of muscle, `Ca^(2+)` ions are released from sarcolasmic reticulum to sarcoplasm and vice versa occurs during relaxation it requires constant plugging in and out of `Ca^(2+)` ions from sarcoplasmic reticulum. |

The pivot joint between atlas and axis is a type ofA. fibrous jointB. cartiaginous jointC. synovial jointD. saddle joint |
Answer» Correct Answer - C The joint between atlas and axis is a type of synovial joint. A considerable movement is allowed at all synovial joints. They are surrounded by tubular articular capsule. The capsule consists of two layers, i.e., outer fibrous capsule and inner synovial memberane, nourishment to articular cartilage. Concept Enhancer Fibrous joint. They do not allow movement because the boues are held firmly by bundles of white fibrous tissue. e.g. joint between the bones pubis. Cartilaginous joints They allow slight movement because of the elastic pads of fibrocartiolage present between the ends of the bones taking part in the joints, e.g. pubic symphysis of pubis. Saddle joints This is the type of synovial joints. This type of joint is like ball and socket joint, but not developed fully, e.g. joint between carpal of hand. |
