Humans have an impact on biophysical environment, ecosystem, biodiversity, and natural resources
HOPE THIS HELPS!!!
Answer:
The following steps must be performed to make a bacterium produce human protein X: D) 6, 7, 2, 4, 5, 3, 1
Explanation:
To make a bacterium produce a human protein, it can be genetically modified in order to produce something useful, such as human inslun or human growth hormone. This is the right process in order to have a succesful result:
<em>1- Eukaryotic transcription; </em>
<em>2- Reverse transcription. </em>
<em>3- Restriction enzyme;</em>
<em>4-DNA ligase; </em>
<em>5-Transformation;</em>
<em>6-Prokaryotic transcription; </em>
<em>7-Translation; </em>
A useful model for enzyme action is the Lock and Key model
Answer: Option D
<u>Explanation:</u>
Enzymes are nothing but chemicals which are used to increase the reaction rate such that the reaction gets completed at faster rate. The working mechanism of enzyme can be best understood by the lock and key model which was put forth by Emil Fischer in 1890.
In this model he explains about the relation between the dynamic site of an enzyme and a substrate particle. The dynamic site was thought to have a fixed structure (the lock), which precisely coordinated the structure of a particular substrate (the key).
When the correct substrate fits in the enzyme it causes enzyme and substrate to interact with each other. The substrate is changed over to products and is subsequently discharged, freeing the protein.
Answer:
In summary, during cellular respiration, most electrons travel the following “downhill” route: glucose → NADH → electron transport chain → oxygen.
