<h2>Sugar beet harvest </h2>
Explanation:
Sugar beets have to be harvested and stockpiled in September because they have to get the root out of the ground before the ground freezes
- Sugar beets are harvested with two primary pieces of equipment
- The defoliator removes the green leaves and slices a slab from the top of the sugar beet root
- This removed slab is the growing point of the sugar beet and contains high levels of impurities, which impede the factories ability to extract the sugar from the remainder of the harvested root
- The sugar beet root is then harvested with a pinch wheel harvester, which pinches the root and lifts from the soil
- The sugar beet harvester also separates some soil and conveys the sugar beet into a truck to be transported to a receiving station
Answer:
Explanation:
The theory of uniformatrianism was proposed by James Hutton, a Scottish Geologist by profession.
This theory was a contrast proponent to the tenets of the theory of catastrophism in existence before then in the scientific circles
The theory states that "the present is the key to the past and geologic processes occurring today have happened in the times past".
- The theory correlates geologic processes as continuous in nature rather can punctuated situations.
- Erosion occurring today has been changing the land surface on earth as far back into the geologic times and periods.
- From the image, the erosional activities are still continuing today.
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>
Answer:
Steroid hormones that enter the cell activate receptors. These hormone-receptor complexes then bind HREs and influence gene expression.
Explanation:
Mechanism of action of steroid hormones is as follows:
- Steroid hormone enters cell and bind to the receptor.
- Translocation of activated receptor- ligand complex into nucleus.
- This complex then bind to another receptor on the chromatin.
- Steroid receptors form dimers.
- Act on DNA
- These hormone-receptor complexes then bind HREs and influence gene expression.
- Augmentation or Suppression of transcription.
