What else can I help you with?
Enzymes are carbohydrates that act as catalysts in metabolic reactions true or false?
FALSE!Enzymes are PROTEINS that can act as catalysts in metabolic reactions.
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 .
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.
IS it true that enzymes increase the number of collisions in a chemical reaction?
Enzymes do not increase the number of collisions in a chemical reaction. Instead, they lower the activation energy required for a reaction to occur, thereby increasing the rate of the reaction. This is achieved by providing an alternative pathway for the reaction to proceed.
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

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.
Without enzymes chemical reactions necessary for life would not occur at a rate sufficient to sustain life True or False?
Usually, to have a fast chemical reaction, you want high temperatures. However, it is not favorable to have these high temperatures in cells (for many reasons; ask another question if you want reasons) Therefore, organisms use enzymes to catalyze reactions. Essentially, you're achieving the same goal of a fast reaction by using a different mechanism (enzyme vs. high temp). In sustaining life, you need fast reactions because most reactions occur very very slowly.. The answer to your question is yes..without enzymes chemical reactions necessary for life would not occur at a rate sufficient to sustain life.
True or false - certain carbohydrates are enzymes or catalysts?
False. Carbohydrates are organic compounds made of carbon, hydrogen, and oxygen, primarily serving as energy sources or structural components in organisms. Enzymes and catalysts are typically proteins or RNA molecules that facilitate chemical reactions but are not classified as carbohydrates. While some carbohydrates can have functional roles in biological processes, they do not act as enzymes or catalysts themselves.
Is it true that Enzymes are not consumed during a chemical reaction?
Correct. Enzymes help to speed up chemical reactions. They may speed them up, costing them some energy, but they are never used up.
Atoms can disappear completely in some chemical reactions-true or false?
false. atoms can either be fused or defused in all chemical reaction.
Are chemical reactions that absorb energy will occur without a source of energy?
false
Is it true or false that Enzymes interact with specific substrates?
True. Enzymes are highly specific in their interactions with substrates. Each enzyme is designed to interact with a particular substrate based on the shape and chemical properties of both the enzyme and the substrate. This specificity allows enzymes to catalyze specific reactions efficiently.
True or false the reactions that convert the energy in sunlight into chemical energy of ATP and NADPH are called the Calvin cycle?
False. The reactions that convert the energy in sunlight into chemical energy of ATP and NADPH are part of the light-dependent reactions in photosynthesis. The Calvin cycle, on the other hand, is the series of reactions that occur in the stroma of chloroplasts and are responsible for carbon fixation and the production of sugars.
True or false activation energy is needed only by chemical reactions that release energy?
true activation energy is the minimum amount of energy needed to start a chemical reaction
