Answers
Answer: I hope this helps! Can I have Brainliest plz :)
Explanation:
When the conformations change from A to B, there is less binding of the substrate. So, the correct option is (A).
What is an Enzyme?Enzymes are types of proteins which act as biological catalysts by speeding up chemical reactions. The molecules on which enzymes can act on are called substrates, and enzymes which convert substrates into different molecules known as products.
It speeds up the rate of a specific chemical reaction in the cell. It is not destroyed during the reaction and is used again and again. Enzymes follow the lock and key principle to bind to the substrate i.e. the specific lock binds to the specific key, similarly the specific enzyme binds to the its substrate.
Enzymes perform the important function of lowering the activation energy of a reaction which is the amount of energy required to initiate the reaction. Enzymes work by binding to reactant molecules and holding them in such a way that the process of breaking and forming chemical bonds occurs more easily.
Thus, when the conformations change from A to B, there is less binding of the substrate. So, the correct option is (A).

Which statement below best describes the difference between "cytokinesis" in animal cells and plant cells? (choose all that apply)
In animal cells a cell plate forms and the cells do NOT pinch apart
There is not a difference in cytokinesis in plant and animal cells
In animal cells a cleavage furrow forms and the new cells pinch apart
In plant cells a cell plate forms, the new cells do NOT pinch apart
Answers
The difference between cytokinesis in animal and plant cells is that a cleavage furrow forms in animal cells and the new cells pinch apart.
Cytokinesis is the division of cytoplasm at the end of mitosis leading to the production of 2 independent daughter cells from a single cell.
Animal cells lack a cell wall. Thus, the cell membrane bends inward to form a cleavage furrow that eventually leads to the separation of the new cells.
The presence of a cell wall in plant cells means that a cleavage furrow cannot be formed like animal cells. Instead, a new cell wall, otherwise known as the cell plate, just forms to separate the two nuclei at the opposite poles of the mother cell.
More on cytokinesis can be found here: https://brainly.com/question/221186
Answer:
Plant cells deposit vesicles containing cell wall building blocks on the metaphase plate; animal cells form a cleavage furrow.

what type is anomer?
Answers
Answer:
An anomer is a type of geometric variation found at certain atoms in carbohydrate molecules. An epimer is a stereoisomer that differs in configuration at any single stereogenic center. An anomer is an epimer at the hemiacetal/hemiketal carbon in a cyclic saccharide, an atom called the anomeric carbon.The anomeric carbon is the carbon derived from the carbonyl carbon compound (the ketone or aldehyde functional group) of the open-chain form of the carbohydrate molecule. Anomerization is the process of conversion of one anomer to the other. As is typical for stereoisomeric compounds, different anomers have different physical properties, melting points and specific rotations.

All living organisms break down sugar to obtain energy using cellular respiration, Which of the following chemical reactions represents the process of aerobic cellular respiration
Answers
Answer:
The chemical reaction that represents the process of aerobic cell respiration is oxygen + glucose → water + carbon dioxide + energy
Explanation:
Cell respiration occurs in the mitochondria of eukaryotic cells and consists of a series of chemical reactions in which energy in the form of ATP molecules is obtained from a glucose molecule in the presence of oxygen.
Glucose is the main energetic substrate to be able to synthesize energy in the form of ATP, through oxidative phosphorylation. At the end of the process ATP is obtained as products, and as waste compounds water and carbon dioxide, which can be schematized in the following chemical reaction:
C₆H₁₂O₆ + 6O₂ → 6H₂O + 6CO₂ + ATP ↑
Glucose + Oxygen → Water + Carbon dioxide + Energy ↑
This reaction summarizes what happens in aerobic cellular breathing, which is necessary to synthesize energy for cellular functions.
The other reactions:
oxygen + water → glucose + lactose glucose + lactose → oxygen + water water + carbon dioxide + energy → oxygen + glucosedo not represent the components or the order of the reactions that occur in aerobic cell respiration

Gases hold so much energy that the molecules are moving so quickly they literally jump out of a liquid and begin flying around the room. It is at this temperature that a substance is holding as much heat energy as it can hold, so it's temperature stops increasing, even if more heat is added.

They were correct, the proteins do go there.
Answers
Answer: A. Proteins are hydrophobic, so they shouldn’t be in an aqueous environment.
Explanation: ummm Founder Education
Membrane proteins are part of the biological membranes. Proteins are hydrophobic, and lacking in an aqueous environment was the drawback of the Davson-Danielli model. Thus, option A is correct.
What is Davson-Danielli model?
Davson-Danielli gave the membrane model, which was also called a lipoprotein sandwich model. It was proposed to show the selective nature of the membrane structure and resembles a sandwich due to its structural organization.
The lipids were layered in between the two protein layers on either side making it look like a sandwich, but the model was rejected as it didn't explain certain permeable molecules.
The arrangement was also contradictory as the proteins are hydrophobic and were placed on the outer side making them exposed to the water molecules. This constricted the movement, and the model failed.
Therefore, the hydrophobic nature of the protein failed the Davson-Danielli model.
