Why are endergonic and exergonic reactions are said to be coupled in living cells?
Endergonic reactions absorb energy, while exergonic reactions release energy. In living cells, these reactions are coupled so that the energy released from exergonic reactions can be used to drive endergonic reactions. This coupling allows cells to maintain energy balance and perform essential functions.
Which is an epidermal cell with an immunological function?
Langerhans cells are epidermal cells that play a key role in the immune response by capturing and presenting antigens to immune cells. They are part of the skin's immune system and help in defending against pathogens.
Is chemical reactions needed to build new cells?
Yes, chemical reactions are essential for the creation of new cells. These reactions involve the synthesis of new molecules such as proteins and nucleic acids, which are building blocks of cells. Without these chemical processes, cells would not be able to grow and reproduce.
Most chemical reactions within cells not take place without what?
Most chemical reactions within cells could not take place without....WATER! water also helps cells keep their size and shape and keeps the temperature of cells from changing rapidly
What kind of reactions occur in cells?
Cells undergo a variety of biochemical reactions essential for life, including metabolic pathways such as glycolysis, the Krebs cycle, and oxidative phosphorylation, which generate ATP for energy. Additionally, cells engage in anabolic reactions to synthesize macromolecules like proteins, nucleic acids, and lipids from smaller units. Catabolic reactions break down substrates to release energy and recycle cellular components. Moreover, cells participate in signaling reactions that facilitate communication and respond to external stimuli.
Chemical reactions in cells are faster than the same reactions outside cells?
Chemical reactions in cells are faster than the same reactions outside cells.
What has an immunological function and is not present in adults?
The thymus gland has an immunological function and is primarily active in children, playing a crucial role in the development of T-cells, which are essential for the immune response. As individuals reach adulthood, the thymus gradually shrinks and becomes less functional, leading to a decreased production of new T-cells. While remnants of thymic tissue may remain, the gland is not as prominent or active in adults as it is in children.
What are the immune cells that produce free antibodies?
B lymphocytes that will divide to form 1.plasma cells which produce specific antibodies and 2.memory cells which is the basis of immunological response.
What is body's antibody maker?
chuck norris
Where does The reactions of photosynthesis occur in the of plant cells.?
The reactions of photosynthesis occur in the chloroplast in the cells in plants.
Which term describes leukocytes that provide immunological defenses against many infectious organisms?
Leukocytes are white blood cells
Are Chemical reactions in cells faster than the same reactions outside cells?
Yes, chemical reactions in cells are generally faster than the same reactions outside of cells. This is due to the presence of enzymes in cells that catalyze and speed up reactions by lowering the activation energy required for the reaction to occur. Additionally, cells are able to control and optimize the conditions for these reactions to take place efficiently.
Why are endergonic and exergonic reactions are said to be coupled in living cells?
Endergonic reactions absorb energy, while exergonic reactions release energy. In living cells, these reactions are coupled so that the energy released from exergonic reactions can be used to drive endergonic reactions. This coupling allows cells to maintain energy balance and perform essential functions.
How do red blood cells protect you?
Red blood cells provide oxygen from the lungs to the various tissues in the body, and in so doing return CO2 to the lungs to be breathed out. They don't serve an immunological function.
The cells that perform immunological surveillance are the?
cells include natural killer (NK) cells and certain types of T lymphocytes, such as cytotoxic T cells. These cells are part of the innate and adaptive immune systems and help to identify and eliminate infected or abnormal cells in the body.
Chemical reactions that occur in cells are called biochemical reactions?
yes. true.
Which is an epidermal cell with an immunological function?
Langerhans cells are epidermal cells that play a key role in the immune response by capturing and presenting antigens to immune cells. They are part of the skin's immune system and help in defending against pathogens.
