What else can I help you with?
Is a catalyst normally required in biochemical reactions?
Yes. A catalyst (AKA enzyme, in biochemical reactions) bonds to reactants and lowers the activation energy required for the reaction to take place. (It makes it require less energy to happen.) After the reaction is finished, the enzyme unbinds and can be reused. Catalysts are used to speed up biochemical reactions; for example, without enzymes, the food you ate a month ago wouldn't be digested and would still be sitting in your stomach today. Enzymes can be denatured (lose their shape) by extreme heat or acid. If it is denatured then it cannot perform a biochemical reaction.
How is oil used to release energy?
{In the banner, Biochemistry was put beside Wood-Burning Stoves for this Reason: The Biochemical Equation that Describes Photosynthesis is the exact opposite of the Biochemical Equation that Describes Respiration.}The Chemical Reactions that describe Combustion - the combining of hydrocarbons [oil for example] with Oxygen to produce H2O and chemical [thermal] energy - Heat - and CO2 - are identical to the Biochemical reactions that describe Respiration.
What does high heat do to enzymes?
High heat can denature enzymes, disrupting their structure and functional shape. This can render the enzymes inactive or reduce their efficiency in catalyzing biochemical reactions. Additionally, prolonged exposure to high heat can lead to irreversible damage to enzymes.
Can a male dog bring your dog back in heat?
No, It will happen evey six months no matter what you do.
What name is given to all chemical reactions which releases heat energy?
Exothermic reactions produce heat. Endothermic reactions take in heat from the surrounding area and get cold.
Do chemical reactions need heat to start them off?
Endothermic reactions need heat.
Why is a heat filter used for photosynthesis?
A heat filter is used to regulate the temperature during photosynthesis to optimize enzyme activity and biochemical reactions. Photosynthesis can be affected by extreme temperatures, so a heat filter helps to maintain an ideal temperature range for efficient photosynthetic processes.
Do all acid reactions give off heat?
Not all acid reactions give off heat. Some acid reactions are endothermic, meaning they absorb heat from the surroundings instead of releasing it. Examples of endothermic acid reactions include the reaction of citric acid with water.
Is heat liberated in endothermic reactions?
No. Heat is given out (liberated) in exothermic reactions not endothermic. exo = out, therm = heat. Endothermic reactions take in heat energy from the surrounding wshich cause the surrounding temperature to decrease. endo = in.
Is the spontaneity of reactions always associated with exothermic heat release?
No, the spontaneity of reactions is not always associated with exothermic heat release. Some spontaneous reactions can be endothermic, meaning they absorb heat from their surroundings.
Contrast endothermic and exothermic reactions?
Endothermic reactions are chemical reactions that use heat as part of the reactant. Heat is absorbed into the reaction in order for it to continue. Exothermic reactions are chemical reactions that release heat as a product of the reaction.
What is an another name for exothermic and for endothermic reactions?
it is a Many chemical reactions release energy in the form of heat, light, or sound. These are exothermic reactions. Exothermic reactions may occur spontaneously and result in higher randomness or entropy (ΔS > 0) of the system. They are denoted by a negative heat flow (heat is lost to the surroundings) and decrease in enthalpy (ΔH < 0). In the lab, exothermic reactions produce heat or may even be explosive. There are other chemical reactions that must absorb energy in order to proceed. These are endothermic reactions. Endothermic reactions cannot occur spontaneously. Work must be done in order to get these reactions to occur. When endothermic reactions absorb energy, a temperature drop is measured during the reaction. Endothermic reactions are characterized by positive heat flow (into the reaction) and an increase in enthalpy (+ΔH).
