Below is a micrograph o xzn;u 3z62 kraio k2224(ie zxyg/8miwr:dmaf mitochondria with four structures or locations labelled. Which is a correct description of how on z/ i2:(24igex2a my rm8k owdie of these structures is adapted to its function?
A. Structure is P, Adaptation and function is Projections to increase surface area for the electron transport chain
B. Structure is Q, Adaptation and function is Contains enzymes required by the link reaction and Krebs cycle
C. Structure is R, Adaptation and function is Large surface area for oxidative phosphorylation
D. Structure is S, Adaptation and function is Barrier between the inner parts of the mitochondrion and the cytoplasm which creates an ideal space with optimum conditions for cellular respiration
参考答案: C
本题详细解析:
P is the outer mitochondrial membrane (Choice A). Ijzf4l- ak xfnfrzbp5.x 7(21y t acts as a barrier between the inner part of the mitochondrion and the cytoplasm which creates an ideal space with optimum conditions for cellular respiration.
Q is the innef z4 5(1nx p-rl7a.zfk2xybf jr mitochondrial membrane (Choice B) where the electron transport chain and ATP synthase are located.
R is the cristae, which are projections of the inner mitochondrial membrane which has a large surface area for oxidative phosphorylation to take place.
S is the matrix (Choice D) where enzymes required for the Krebs cycle and link reaction are found.
