Colt1911 [192]

Answer:

c. Increasing temperature above the optimal value slows the reaction rate

Explanation:

Enzyme activity is  affected by factors, such as temperature, pH, and concentration.

The rate of an enzyme-catalysed reaction increases as the temperature increases. However, increasing the temperature above the optimal value slows the reaction rate because the enzyme becomes denatured and can no longer function.

Thus, the correct option is "C"

c. Increasing temperature above the optimal value slows the reaction rate

The polypeptide encoded by the glucose carrier gene has a signal sequence. As a result, the ribosome and the polypeptide that is
olganol [36]

Answer:

The correct words for the three blanks are as follows:

1. Endoplasmic reticulum. 2. Golgi apparatus. 3. Facilitated diffusion.

Explanation:

During the translation stage of protein synthesis, signal sequences are either attached or excluded from a synthesized protein in order to indicate the right location it should be sent to. Proteins that possess signal sequences are usually sent to the endoplasmic reticulum, where they will be folded into their right shapes. From the endoplasmic reticulum the proteins are then transported into Golgi apparatus via membrane vesicles. In the Golgi apparatus, proteins undergo their final modifications before they are transported to their final destinations. The final destination of glucose carrier proteins is the plasma membrane, where they help glucose molecules to enter the cell via facilitated diffusion.

Identify three things that can increase the rate of mutation
Alenkasestr [34]

Some chemicals increase the mutation rate, physical agents such as radiation also increase the mutation rate. There are viruses that are mutagens as well. Also, the number of mutations that an organism produce can also be phenotypically plastic.

Hope this helps. (This is the definition my bio teacher gave me.)
