What else can I help you with?
Is transport a function of a protein?
Transport protein provide channels for certain solutesTransport proteins are embedded in cellular membranes. They permit the passage across the membrane of substances that cannot pass through the phospholipid bilayer.Substances may pass through transport proteins by diffusion (often called facilitated diffusion because these substances cannot pass through any other part of the membrane) or by active transport.Transport proteins are subdivided into categories, such as channel proteins and carrier proteins, depending on details of their functioning.
Explain why some plasmids contain a gene for resistance to an antibiotic?
Plasmids provide a mechanism for horizontal gene transfer within a population of microbes and typically provide a selective advantage under a given environmental state. Plasmids may carry genes that provide resistance to naturally occurring antibiotics in a competitive environmental niche, or the proteins produced may act as toxins under similar circumstances.
Which of molecules are often embedded within the lipid bilayer to help substances through the membrane?
Proteins known as membrane proteins are often embedded within the lipid bilayer to facilitate the transport of substances across the membrane. These include channel proteins, which provide passageways for specific ions and molecules, and carrier proteins, which bind to substances and change shape to shuttle them through the membrane. Additionally, aquaporins are specialized channel proteins that specifically aid in the transport of water. Together, these proteins play a crucial role in regulating cellular transport and maintaining homeostasis.
What are the parts of the membrane help large molecules pass through it?
Globular proteins.
What materials and proteins are transported through through the cells?
By the chromosomes
How do proteins provide energy for cellular processes?
Proteins provide energy for cellular processes through the breakdown of amino acids, which can be converted into energy through metabolic pathways such as glycolysis and the citric acid cycle. This energy is then used by the cell to carry out various functions and activities.
Is air a source of resistance?
Yes, air can provide resistance to objects moving through it. This resistance, known as air resistance or drag, is caused by air molecules colliding with the moving object and can slow down its motion.
Do channel proteins provide a continuous path across the membrane?
Yes, only channel proteins provide a continuous path across the plasma membrane. Carrier proteins do not provide a continuous path but do require conformational changes in order to transport solutes across the membrane.
What Contains information for synthezing proteins?
The information for synthesizing proteins is contained in the cell's DNA. Genes within the DNA provide the instructions for making proteins through a process called protein synthesis, which involves transcription of DNA into mRNA, and translation of mRNA into proteins by ribosomes.
Why does the oscillation of a pendulum gradually slows down after a certain interval of time?
Energy is gradually lost, through air resistance, and resistance in the string.Energy is gradually lost, through air resistance, and resistance in the string.Energy is gradually lost, through air resistance, and resistance in the string.Energy is gradually lost, through air resistance, and resistance in the string.
Why do wires turn hot in a circut?
Wires turn hot in a circuit due to the resistance they provide to the flow of electric current. This resistance causes energy to be converted into heat as the current passes through the wire. The higher the current flowing through the wire, the more heat is generated.

Why Proteins do not pass through cell membranes?
Hydrophilic proteins.
How the complex proteins are made?
Complex proteins are made the same way as regular proteins; through translation.

How do mitochondria contribute to the creation of proteins within the cell?
Mitochondria provide the energy needed for protein synthesis by producing ATP through cellular respiration. This energy is essential for the process of translation, where ribosomes use mRNA to assemble amino acids into proteins.
