Answer:

The second statement is incorrect.

Explanation:

The proteins generated in the rough endoplasmic reticulum can be sorted to the cell membrane, Golgi apparatus, exterior to the cell, and lysosome.

As a component of microtubules tubulin is found in cytoplasm and these proteins of cytoplasm originate due to the translation process undergone by the cytoplasmic ribosomes, not by the ribosomes present on the rough endoplasmic reticulum. Thus, these proteins are not a component of endomembrane system.

Which statement is TRUE regarding the glycolytic pathway?

Westkost [7]

Answer:

d) All of the statements are true.

Explanation:

 It includes reactions catalyzed by three isomerase enzymes.

The statement is true because:

The first reaction which involve isomerase is the conversion of glucose 6-phosphate into fructose 6-phosphate with the help of an enzyme phosphoglucose isomerase.

The second reaction is conversion of dihydroxyacetone phosphate (DHAP) into glyceraldehyde 3-phosphate with the help of an enzyme triphosphate isomerase.

The 3rd reaction is conversion of 3-phosphoglycerate to 2-phosphoglycerate.

It includes five phosphate transfer reactions.

The statement is true because:

1. The conversion of glucoe to glucose 6-phosphate.

2. The conversion of fructose 6-phosphate to fructose 1,6-biphosphate.

3.The conversion of glyceraldehyde 3-phosphate to 1,3-biphosphoglycerate.

4. The conversion of 1,3-biphosphoglycerate to 3-phosphoglycerate.

5. The conversion of phosphoenol pyruvate to pyruvate.

It includes three enzymes that are regulated by product inhibition.

The statement is true because:

1. Hexokinase which is inhibited by its product glucose 6-phosphate.

2. Phosphofructokinase which is inhibited by ATP.

3. Pyruvate kinase which is also inhibited by ATP.

Thus, all the statements are correct.

Identify 3 solutions to the issue of human impact on the environment

slega [8]

Explanation:

1.) taking trains or riding bicycles to destinations.

When you do this, it produces a lot less carbon emission, contributing less to the greenhouse effect and global warming. (And with bicycles, it produces none!)

2.) Quit littering on the ground, throw it in the trash!

When you litter, that can get trash in oceans and animals habitats. In oceans, fish can get stuck in a plastic ring or cup, casing it to die.

If you, for instance, throw a cigarette on the ground, an animal could eat it. The gasoline, paint, paper, and tobacco can severely injure an animal, or even kill it. When a predator sees this animal, they could eat it, causing the tobacco to get into the predator, which could also kill the animal as well.

3.) Recycle.

When you recycle, less trash goes into landfills (which are super bad for the environment). Recycling things makes them reusable! If you have a plastic water jug, instead of throwing it away, fill it with other water and store it for just in case. Recycling things depletes the amount of trash being produced and thrown into oceans and other habitats.
