Proteins build up cells and control their chemical reactions by means of enzymes which is a natural catalyst.
What else can I help you with?
Do prokaryote cells contain organelles?
They do but the organelles are not bound in membranes.
These are primary molecules making up plasma membranes in cells?
Phospholipids are the primary molecules that make up plasma membranes in cells. Other important molecules include cholesterol, glycolipids, and proteins. These components help maintain the structure and function of the plasma membrane.
What part of the cell enters the cell and leaves?
The only things that enter and leave cells are molecules and proteins. organelles do not leave the cell.
Are organelles the same as macromolecules?
No, organelles are specialized structures within cells that perform specific functions, while macromolecules are large molecules such as proteins, carbohydrates, lipids, and nucleic acids that make up the structure of cells. Organelles contain macromolecules, but they are not the same thing.
Which molecules help control movement of substances through cell membranes?
Proteins such as transporters, channels, and pumps are the main molecules that help control the movement of substances through cell membranes. These proteins facilitate the selective transport of ions, molecules, and other substances into and out of cells, maintaining proper cellular function. Additionally, phospholipids in the membrane also play a role in regulating the movement of substances across the cell membrane.
What organelles are found in proteins?
well, ribosomes make proteins within a cell, but mitochondria have proteins.
What is the main substance from which cells are constructed?
Cells are mainly constructed from lipids, proteins, nucleic acids, and carbohydrates. These organic molecules form the basic structural components of cell membranes, organelles, and other cellular structures.
Do prokaryote cells contain organelles?
They do but the organelles are not bound in membranes.
Do Eukayote cells have membrane bound organelles?
Yes, the organelles in eukayote cells are wrapped in membranes.
These are primary molecules making up plasma membranes in cells?
Phospholipids are the primary molecules that make up plasma membranes in cells. Other important molecules include cholesterol, glycolipids, and proteins. These components help maintain the structure and function of the plasma membrane.
Which best describes a difference between prokaryotic cells and eukaryotic cells?
Eukaryotic cells contain organelles that are enclosed in membranes
What part of the cell enters the cell and leaves?
The only things that enter and leave cells are molecules and proteins. organelles do not leave the cell.
What organelle is made up of one single cell?
There are none. Organelles are found IN cells. They are made up of membranes and proteins. An organelle to a cell is like an organ to a human.
Are cells a type of protein?
No, cells are composed of all macromolecules: proteins, lipids, carbohydrates, and nucleic acids. Cells definitely contain protein in the membranes and organelles, but they're not wholly made up of protein or are a type of protein.
What role do proteins play in the structure and function of plasma membranes?
Proteins in plasma membranes help maintain the structure and regulate the functions of cells by serving as channels for molecules to enter and exit the cell, as well as facilitating cell signaling and recognition.
What are cells that have internal membranes surrounding organelles?
Animal and Plant cells have internal membranes surrounding organelles. Animal cells have a cell membrane protecting the organelles. Plant cells have a cell membrane as well as a cell wall surrounding organelles.
Are organelles the same as macromolecules?
No, organelles are specialized structures within cells that perform specific functions, while macromolecules are large molecules such as proteins, carbohydrates, lipids, and nucleic acids that make up the structure of cells. Organelles contain macromolecules, but they are not the same thing.
