What is a system of double membranes that make lipids?
Endoplasmic Reticulum
A system of double membranes that make lipids is called?
Endoplasmic Reticulum
What are chemical that can change the rates of chemical reactions in nonlivings system?
These chemicals are called catalysts.
When a chemical reactions takes place in an closed system?
Mass is constant.
What is true about chemical reactions in a closed system?
In a closed system, matter cannot enter or leave the system, but energy can still be exchanged with the surroundings. Chemical reactions in a closed system will reach equilibrium, where the rates of the forward and reverse reactions are equal and the concentrations of reactants and products remain constant. The total amount of matter in the system will not change during a reaction in a closed system.
What recognizes a hormone's chemical structure in the endocrine system?
Hormone receptors on cell membranes recognize a hormone's chemical structure in the endocrine system. When the hormone binds to the receptor, a cell changes its behavior.
What is the relationship between exothermic reactions and entropy changes in a chemical system?
In a chemical system, exothermic reactions release heat energy, while entropy changes refer to the disorder or randomness of molecules. Exothermic reactions typically lead to an increase in entropy, as the released heat energy can increase the movement and randomness of molecules in the system.
Why are exothermic reactions chemical reactions?
Exothermic reactions are chemical rections since these affects the composition and chemical properties of a matter and result in the formation of new substance. Example burning of coal , electrolysis of water.
What is importance of enzyme?
They carry out chemical reactions to the cells and breaks down things to be digested. They also allow many chemical reactions to occur within the homeostasis constraints of a living system.
What is the role of a redox buffer in maintaining the balance of electron transfer reactions in a chemical system?
A redox buffer helps to maintain the balance of electron transfer reactions in a chemical system by accepting or donating electrons as needed. This helps to stabilize the system and prevent excessive buildup of reactive species, ensuring that the reactions proceed smoothly and efficiently.
Which occurs when the forward and reverse reactions occur at the same time?
Chemical equilibrium occurs when the forward and reverse reactions in a chemical system occur at the same time, resulting in no overall change in the concentrations of reactants and products. At equilibrium, the rates of the forward and reverse reactions are equal, and the system is said to be in a state of dynamic balance.
What is A system of membranes that appears to be a factory for life processes and a cell communication system for chemical messages?
The endoplasmic reticulum is a system of membranes in the cell that is involved in protein synthesis, lipid metabolism, and detoxification. It also plays a role in the communication between cells through the transport of chemicals.
