Answer:
So that oxidation of pyruvate can take place in mitochondria.
Explanation:
Pyruvates is produced in the glycolysis process which occurs in the cytoplasm. So pyruvate is produced in the cytoplasm of the cell. Pyruvate is produced by partial oxidation of glucose and to be fully oxidized it has to enter in the mitochondria.
So after entering the mitochondria the pyruvate first converts into acetyl CoA than this acetyl CoA enters in the citric acid cycle and fully oxidized into CO2. This oxidation generated NADP and FADH2 which provide reducing power during oxidative phosphorylation.
Tadpoles have gills allowing them to breathe underwater while frogs have lungs. Tadpoles have tails and fins to help them swim while frogs have arms and legs.
Mammalia (mammals) have hair or fur and produce milk
Answer:
The steps that can be seen in this story are observation and the questioning phase, which can also be called elaboration of the problem.
Explanation:
The scientific method is a set of phases that are able to guide researchers to the creation of scientific knowledge, through an experiment. This method is essential for conducting scientific research, allowing an experiment to be managed in a way that promotes answers to scientists' questions. The scientific method presents the phases called observation, questioning (or elaboration of the problem), elaboration of hypotheses, experimentation, analysis of the results and conclusion.
In the story shown in the question above, we can see the phases called observation and questioning. The observation takes place the moment Fleming noticed a fungus capable of growing on colonies of bacteria that cause throat infections, killing them. This observation made him enter the questioning phase, when he wondered if the fungus was able to prevent the growth of these bacteria.
Answer:
b) The hydrolysis of ATP helps "pay for the formation of a thioester involving CoA-SH.
Explanation:
In the citrate cycle, we know that lysis is mediated by the hydrolysis of ATP, which is the fuel of the reaction, so the correct answer is B. The hydrolysis of ATP helps "pay for the formation of a thioester involving CoA-SH.
