AQA A-level BIOLOGY (7402/1) Paper 1 PREDICTION QUESTIONS AND ANSWERS 2024 SPECIMEN VI Question 1: (a) Describe what is meant by the term 'metabolic rate'. [2] (b) Explain how the control of body temperature is an example of homeostasis. [4] Answer 1: (a) 'Metabolic rate' refers to the rate at which chemical reactions occur within an organism's cells. It's a measure of the amount of energy expended by an organism per unit of time. (b) The control of body temperature is...

Muscle movement on the cellular level is initiated by the release of Ca2+ from the terminal cisternae. Terminal cisternae are associated with A. sarcoplasmic reticulum. B. myosin cross-bridges. C. myoglobin. D. canaliculi. E. thin filaments. - correct answer A Muscle fibers store Ca++ in the sarcoplasmic reticulum for release during contraction. The sarcoplasmic reticulum, analogous to the endoplasmic reticulum, runs extensively throughout the fiber so that released Ca++ will come ...
