In biology, what is a cell membrane and its functions? Which structure composed mainly of proteins and lipids, aids in maintaining homeostasis in the cell? (a) Chromosome (b) Centrosome (c) Nucleolus (d) Cell membrane (e) Cell wall ...
1. Which of the following is NOT a characteristic of a prokaryotic cell? a. A semi-fluid region consisting of cytosol b. Membrane-bound cellular organelles c. Plasma membrane consisting of lipids and proteins d. Ribosomes that synthesize proteins e. R ...
Controlling lipids: what the evidence shows; Combing through the best and latest trials, our experts synthesize the findings into this useful primer on one of your most frequent diagnoses.(usage of lipid lowering therapy )Stubbs, Nancy D
It synthesizes lipids, phospholipids as in plasma membranes, and steroids. Cells that secrete these products, such as cells of the testes, ovaries, and skin oil glands, have an excess of smooth endoplasmic reticulum. What are cisterns in biology class 9? Answer: A reservoir or a closed ...
2.lipids 3.proteins 4.nucleic acids Carbohydrates and lipids store energy in the cell, form structural components and act as chemical messengers. Proteins perform similar roles but also set off the chemical reactions that make life possible and affect gene activity. Nucleic acids store the organism...
The basal body is a set of rings embedded in the cell wall and plasma membrane. It consists of 2 pairs of rings in Gram-Negative bacteria and 1 pair of rings in Gram-Positive bacteria. It synthesizes polymers of the flagellum, produces energy for revolution, and regulates movements of the...
2.2 Cell Biology Cell biology is the study of a cell as an individual unit, exploring physiological processes and mechanisms that allow life processes to operate at the molecular level, including cellular structure, division, energy exchange, signaling pathways, and more. Cell biology research studies...
Lipid metabolism is the synthesis and degradation of lipids in cells, involving the breakdown or storage of fats for energy and the synthesis of structural and functional lipids, such as those involved in the construction of cell membranes. In animals, these fats are obtained from food or are ...
The two pathways of both species synthesize primary bile acids which are subsequently converted in the liver by bile salt export protein (BSEP) and bound to taurine (T) or glycine (G) in a 1:3 ratio. These forms conjugated bile acids T/G-CA and T/G-CDCA, catalyzed by bile acid-CoA...
They possess peptidoglycan in their cell walls, which helps maintain structure. Archaebacteria, on the other hand, lack peptidoglycan and have different membrane lipids, allowing them to thrive in extreme environments such as acidic hot springs or high-salt areas. 11 Eubacteria generally reproduce ...
