What else can I help you with?
Almost all enzymes are proteins true or false?
Sort of Enzymes are proteins that increase the rate of chemical reations, they convert molecues from substrates ( a substrate is a molecue upon which an enzyme atc acts ) to products(a product is something "manufactured" by an enzyme from its substrate)Definition in link below.
Hydrophilic ends of proteins are oriented toward membrane surfaces. true or false?
False. Hydrophilic ends of proteins are oriented away from the membrane surfaces, as they interact with the aqueous environment outside or inside the cell. This allows them to interact with water molecules and maintain stability within the cell membrane.
When an enzyme binds with its substrate the activation energy needed for the chemical reaction to occur is increased True or False?
False. When an enzyme binds with its substrate, the activation energy needed for the chemical reaction is decreased, not increased. This reduction in activation energy allows the reaction to occur more quickly and at lower temperatures, making it easier for the reaction to proceed.
Who was the scientist that proved that not all enzymes are proteins?
The scientist who proved that not all enzymes are proteins was Leonor Michaelis and Maud Menten in 1913. Their work on enzyme kinetics showed that enzymes can also be composed of RNA molecules, known as ribozymes. This discovery challenged the prevailing notion at the time that all enzymes were proteins.
Is an organ a group of specialized cells that secrete fluids used in elsewhere in the body?
No, an organ is a structure composed of different tissues serving a specific function in the body. While some organs do secrete fluids like hormones or digestive enzymes, the primary role of an organ is to perform a specific task within an organism.
One particular reactant can only produce one type of product regardless of the enzymes true of false?
False. Enzymes can catalyze multiple reactions, converting one reactant into multiple products. The specificity of an enzyme depends on its active site, which is tailored to bind to specific substrates and facilitate specific chemical reactions.
What are false substrates?
False substrates are molecules that resemble the natural substrate of an enzyme but cannot be acted upon by the enzyme. They compete with the actual substrate for the enzyme's active site, inhibiting the enzyme's normal function. This can lead to a decrease in enzyme activity and disrupt biochemical pathways.
All enzymes function optimally at pH equals 7.4 . true or false?
False. While some enzymes may function optimally at a pH of 7.4, not all enzymes have the same optimal pH. Enzymes can have a range of pH values at which they function best, depending on their specific structure and function.
Do One enzymes can be used for many different types of chemical reactions is this true or false?
True. Some enzymes are able to catalyze multiple types of chemical reactions due to their flexible active sites that can accommodate different substrates. This versatility allows them to participate in various metabolic pathways within an organism.
Are all of the chemical recations that take place in the body require the help of specific proteins called phytochemicals?
false. the correct answer is enzymes
What proteins act as catalysts in mediating and speeding specific chemical reactions?
Enzymes are proteins that act as catalysts in mediating and speeding specific chemical reactions in biological systems. They lower the activation energy required for a reaction to occur, making the reaction proceed faster. Enzymes are highly specific, each one catalyzing a particular reaction or a group of related reactions.
Do Organ systems do not interact with one another true or false?
The answer is "False"
True or False Enzymes are inorganic catalysts?
False. The activation energy of the reaction remains the same. Enzymes split up the reaction pathway into fewer steps, so that less activation energy is required at each step. This allows each step to occur at a lower temperature, or more quickly at the same temperature.
Why does molecules react with enzyme?
In order to do its work, an enzyme must unite - even if ever so briefly - with at least one of the reactants. In most cases, the forces that hold the enzyme and its substrate are noncovalent, an assortment of hydrogen bonds, ionic interactions and hydrophobic interactions. For more information, click the link on the left. Michaelis and MENTON have proposed a hypothesis called complex hypothesis the enzyme substrate compex is an intermediate or transiet complex and bonds involved H.bond vaner waals force sometimes 2 substrates can bind to an enzyme molecule and such reaction are callad as BISUBSTRATE REACTION.
Catalyst are always enzyme it's true or false?
False . Catalysts can be many things ; enzymes and transition elements and their compounds , for example .So Enzymes are always catalysts but Catalysts are NOT always enzymes .
Almost all enzymes are proteins true or false?
Sort of Enzymes are proteins that increase the rate of chemical reations, they convert molecues from substrates ( a substrate is a molecue upon which an enzyme atc acts ) to products(a product is something "manufactured" by an enzyme from its substrate)Definition in link below.
Is this true or false enzymes can help many different they are not specific in their functions?
no, every enzyme has a different shape giving it a different job or function
