Answer:
The correct answer is option A, that is, cytochrome c oxidase.
Explanation:
A sequence of complexes, which conduct electrons from electron donors to electron acceptors through redox reactions, that is, both oxidation and reduction reactions taking place simultaneously is termed as the electron transport chain. This conduction of electrons is further combined with the mediation of protons across a membrane.
Four membrane-bound complexes are present within the mitochondria, of these in complex IV or cytochrome c oxidase, the withdrawal of 4 electrons takes place from 4 molecules of cytochrome c, and is mediated towards the molecular oxygen, which further gives rise to 2 molecules of water. During the process, 8 H+ are withdrawn from the mitochondrial matrix, which contributes to the proton gradient.
The choices can be found elsewhere and as follows:
a. membranes lower the activation energy of biochemical reactions.
<span>b. reactants are within close proximity to each other. </span>
<span>c. membrane-bounded organelles act as catalysts for biochemical reactions. </span>
<span>d. reactants move faster within membrane-bounded organelles. </span>
<span>e. reactants are less likely to encounter each other within membrane-bounded organelles. </span>
The correct answer is option C. Membrane bounded organelles facilitate faster chemical reactions because it <span>act as catalysts for biochemical </span>reactions. Hope this answers the question.
It illustrates the cycling of matter, just like in a natural ecosystem.
Option D.
<h3><u>Explanation:</u></h3>
The natural stable ecosystem is defined as the ecosystem which has the members doing their part of job and each and every member contribute to the stability of the ecosystem by completing food chains.
Here in this bottle ecosystem the boy put the stones, rocks, water which gives proper nutrition to the growing plants and animals which are also introduced by the boy. The plants produce oxygen and consume carbon dioxide whereas the animals consume oxygen and produce carbon dioxide. Thus the cycle is maintained and stability is achieved.
Answer:
Blood
Explanation:
Connective tissue consists of extracellular matrix and cells. The main function of connective tissue is to bind the other tissues together, provide them support and strength. Blood is one of the liquid connective tissue that does not perform such functions. The presence of liquid extracellular matrix (plasma) and formed elements (blood cells) makes it a connective tissue. It serves in the transport of nutrients, gases, wastes, hormones, etc. It also takes part in immune responses but does not strength or support other body tissues.
Answer:
I know im like 2 years late but the answer is d.
Explanation:
It'll always be the one where they are all together and all at or close to the exact target
