Answer 1

I'm pretty sure:

a) pepsin optimal pH: 3 and lipase optimal pH:8

b) No, because the stomach needs to be acidic and have an acidic pH but lipase is considered alkaline because its optimal pH is between 8-14 meaning it's an alkaline.

Not sure if this is any help but I hope it helped a little bit! :)

If fewer cows are now producing more milk, what natural resources are saved in the dairy industry? What resources might be used more.

Answers

Answer:

used less: water, grass, hay, and wheat.

used more: bottles, plastic, carboard (for boxing), wood (box crates).

Explanation:

The natural resources that would be saved in such a scenario are the ones being used to maintain the cows alive and healthy. These include water, grass, hay, and wheat. These natural resources are saved because fewer cows need to be maintained for the same or more amount of milk to be produced. With more milk being produced means all of the resources needed for packaging and selling the milk will be used more, such as bottles, plastic, cardboard (for boxing), wood (box crates).

How do enzymes act as catalysts? (Choose ALL that apply) They allow for fewer collisions of molecules (enzymes + substrates) They allow for more collisions of molecules (enzymes + substrates) They raise the amount of activation energy needed to complete the reaction They lower the amount of activation energy needed to complete the reaction They speed up chemical reactions to form more products

Answers

Answer:

- They allow for more collisions of molecules (enzymes + substrates)

- They lower the amount of activation energy needed to complete the reaction.

- They speed up chemical reactions to form more products

Explanation:

Enzymes are proteinous molecules that serves as catalyst in living systems. Like every other catalyst, enzymes function to SPEED UP the rate of biochemical reactions by LOWERING/REDUCING the activation energy, which is the energy required for a reactant to form product (completion of reaction).

Enzymes like other catalysts causes faster movement of molecules in the reaction i.e. they allow for more collisions of molecules (enzymes + substrates). This causes the rate of reaction to increase and hence, speeden the reaction.

Answer:

they lower the activation energy

7. Ribosome-

Answers

Answer:

you just need to explain to your teacher how each part helps the cells

heres the answers:

1. Cell- work together with similar cells to form structures called tissues.

2. DNA-DNA contains the instructions needed for an organism to develop, survive and reproduce.

3. DNA with a mutation- Mutations range in size; they can affect anywhere from a single DNA building block (base pair) to a large segment of a chromosome that includes multiple genes.

4. Nucleus- The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information.

5. Organism- Organisms respond to stimuli from their environment and actively maintain their internal environment through homeostasis.

6. Proteins- Your body uses protein to build and repair tissues.

7. Ribosome- Within the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis — the stitching together of amino acids to make a protein molecule.

8. Amino acid - When you eat protein, your body breaks the protein down into amino acids. Those amino acids are then used to repair and grow new muscle fibers. When you consume an adequate amount of protein, your body will experience something called a positive balance of nitrogen.
