Answer:
Explanation:
Catalyst is a substance that influences the reaction but does not participate in the reaction
Answer:
Catalyst is a substance that influences the rate of reaction without being consumed in the reaction.
-They increase the rate of reaction by decreasing the activation energy of the reaction.
-As they are not used up in the reaction they are required in a small quantity.
-In biological system, enzymes are referred to as biological catalyst or biocatalyst. They are generally protein in nature and are very specific for their substrate. They also increases the rate of biological reaction by forming enzyme-substrate complex.
-Few examples of catalyst are: potassium permagnet, platinum, enzyme (like hexokinase, hydrolase etc) etc.
Explanation:
I did use someone else's answer from an older post.
SOO.. I forgot the nametag.
A substance that enters the cell without the expense of cellular ATP, but are too large to directly pass through the membrane, use membrane protein in order to gain access to the inside of the cell.
Further Explanation:
The plasma membrane is an outer boundary of the cell. It is composed of phospholipids and proteins. It is also called selectively permeable membrane because it allows only selective substances to cross. Transport across the membrane can be active and passive transport. Active transport requires energy for the movement of substances, whereas in passive transport the molecules move across the membrane without using energy. Water can freely move inside the cell with the help of aquaporins. Also, the osmotic gradient set plays a vital role in the transportation of water.
Glucose and electrolytes require energy to be transported. Facilitated diffusion is a passive movement of the molecules, across the “plasma membrane”, through the aid of the trans membrane protein or substrate-specific protein. This is used by the molecules that are not able to cross the phospholipid layer freely. But, it doesn’t need energy for the transportation process. Glucose is transported by this method.

Correct answer: A). The enzyme influences the speed of change from substrate to product
The enzymes are the biological catalyst that speed up the rate of chemical reactions by decreasing the activation energy of the reaction pathway.
They increase the speed of change of substrate to the product and it remains unchanged in the reaction. Hence, it can be used again and again.
Enzymes are highly specific in nature, only a specific substrate binds to the enzyme's active site. Hence, a particular enzyme is required to catalyze a reaction.
The statement "The enzyme influences the speed of change from substrate to product" is correct. Option 1 is correct.
Enzymes are biological catalysts that speed up chemical reactions by lowering the activationenergy required for the reaction to occur. Enzymes do not undergo any permanent changes during the reaction and are not consumed in the process.
Enzymes are proteins that play a crucial role in biological reactions by facilitating the conversion of substrates into products. Substrates are the specific molecules that bind to the active site of an enzyme, forming an enzyme-substrate complex. The active site is a region on the enzyme's surface that has a complementary shape to the substrate.
When the substrate binds to the enzyme's active site, it undergoes a temporary change in shape, known as the induced fit model. This induced fit brings the reactive groups of the substrate close together, making it easier for the chemicalreaction to occur. As a result, the activation energy required for the reaction to proceed is significantly reduced.
The enzyme does not alter the nature of the reaction or the final products. Instead, it provides an environment where the reaction can occur more rapidly and efficiently. Once the reaction is complete, the enzyme releases the products, and it can then bind to new substrate molecules to catalyze additional reactions.
Enzymes are highly specific, meaning that each enzyme catalyzes a particular reaction with specific substrates. This specificity ensures that only the appropriate substrates bind to the enzyme, preventing unwanted side reactions in the cell.
In summary, enzymes and substrates are related through the process of enzyme-substrate interactions, where enzymes accelerate the conversion of substrates into products by lowering the activation energy required for the reaction. This crucial role of enzymes in biological processes makes them vital for maintaining the proper functioning of living organisms.

Hepatocytes do not produce digestive enzymes.
Hepatocytes are specialized cells found in the liver, and they perform various functions related to metabolism and detoxification. While hepatocytes play a crucial role in processing nutrients, storing fat-soluble vitamins, and detoxifying harmful substances, they do not produce digestive enzymes.
Digestive enzymes are primarily produced by the pancreas and salivary glands, and they are responsible for breaking down food into smaller molecules that can be absorbed and utilized by the body.
