Determination of Caloric Content of Three Foods1. Compare the calorimeter that you built to a bomb calorimeter. How are they sim

ilar and different?2. Although protein was part of the composition of the foods in this experiment, it was not the main macromolecule component of any of the foods. Why do you think a food consisting primarily of protein was omitted from these tests, based on what you learned about the way the fuel is "burned" in the body?

Answer:

The answers to both parts (1 and 2) are given below.

Explanation:

1. The calorimeter is similar to the bomb calorimeter in a way that both measure the changes in heat that occur as result of the chemical reaction taking place inside them. They are different in the sense that a bomb calorimeter provides an isolated system with constant volume and pressure, whereas a regular calorimeter allows pressure to equalize with the environment.

2. Carbohydrates are the molecules that break down and provides energy for cellular functions. Whereas, proteins are not meant for the production of energy but for the production of amino acids to function as structural units for protein synthesis. Simply, the breakdown of protein is for the synthesis of more proteins by providing several units of amino acids rather than the production of energy.

Which of the following genes would not likely be encoded on a plasmid?
raketka [301]

Answer:

gene encoding enzymes for glycolysis.

Explanation:

Plasmid may be defined as an extra chromosomal circular DNA that replicate independently of the main chromosomal material. Plasmid are generally used for the manipulation of genes in molecular technologies.

Plasmid can encode gene for toxins, antibacterial resistance and for the unusual substrate degradation. The plasmid cannot code enzyme for glycolysis because these enzymes are already present in the host organisms. Glycolysis enzymes are independent on the plasmid regulation.

Thus, the correct answer is option (3).

Develop a hypothesis to explain why you think eurypterids developed legs even though they lived on the ocean floor.
expeople1 [14]

I think that since it lives on the ocean floor, at the deepest of the ocean. So anyway, the fin on the Eurypterids is still necessary but not that much, since they live on the ocean floor. Their movements mostly on the ocean floor. So fin would not help them "stick" to the floor. Also there are still gravity acts on the Eurypterids and the feet would help them move faster. Hope this helps.

A (n) inhibitor has a structure that is so similar to the substrate that it can bond to the enzyme just like the substrate. 2. a
Studentka2010 [4]
The answers are as follows:
1. <span>An inhibitor has a structure that is so similar to the substrate that it can bond to the enzyme just like the substrate: t</span>his is called competitive inhibitor. A competitive inhibitor will compete with the substrate for the active site of the enzyme and bind to the active site, thus incapacitating the substrate from binding to the active site.
2.  An inhibitor binds to a site on the enzyme that is not the active site: this is called non competitive inhibitors. Non competitive inhibitors bind to other site in the enzyme which is not the active site of the enzyme. The binding of the inhibitor changes the conformation of the enzyme as well as the active site, thus making it impossible for the substrate to bind to the enzyme effectively.
3. <span>usually, a(n) inhibitor forms a covalent bond with an amino acid side group within the active site, which prevents the substrate from entering the active site or prevents catalytic activity: this is called irreversible or permanent inhibition. Permanent inhibitors form covalent bonds with the enzyme and prevent substrate from binding to the enzyme.
4. T</span><span>he competitive inhibitor competes with the substrate for the ACTIVE SITE on the enzyme: The active site of an enzyme is the place where the substrate normally bind in order to activate a enzyme. Competitive inhibitors are those inhibitors that compete with the substrate for the active site of the enzyme and prevent the substrate from binding there.
5. W</span><span>hen the noncompetitive inhibitor is bonded to the enzyme, the shape of the ENZYME is distorted. The non competitive inhibitors are those inhibitors that bind to other places in the enzyme instead of the active site. The binding of the non competitive inhibitor usually distort the shape and the conformation of the enzyme thus preventing the substrate from binding to it effectively.
6. E</span><span>nzyme inhibitors disrupt normal interactions between an enzyme and its SUBSTRATE. The principal function of enzyme inhibitor is to prevent the substrate from binding to the appropriate enzyme. This is usually done in the human system in order to regulate the activities of enzymes.</span>

The article describes the former abundance of trees and forests on easter island. describe several factors that contributed to t
tester [92]

1. One of the main reasons for the extinction of the trees in the Eastern Island is the extinction or sudden demise of the birds that carried the seeds to different places. Some of the human activities would have also led to the process of extinction, like the trees were being cut to construct canoes and to use as tools in order to erect statues, and to burn them for warmth.  

2. There was a need to farm the trees and manage them in a proper framework. For example, if one is having 100 trees, then one should use 33 and then plant 33 seeds, and should always keep 34 intact. One should have not used all the trees at once.

Butoxors [25]
<span>Nerve cells send electrical impulses along the axon. When these impulses reach the end of the neuron, they cause a release of neurotransmitters across the synapse.
</span>The axon is part of the neuron (nerve cell that carries messages), as well as dendrite. Axons pass the nerve impulses on to other cells, while dendrite <span>receive nerve impulses from other cells. </span><span>The place where the axon of one neuron meets the </span>dendrite<span> of another is called a </span>synapse.
