What are four marcomolecules and their functions?
four major macromolecules are carbohydrates-Energy storage, receptors, structure of plant cell wall; proteins-Enzymes, structure, receptors, transport, and more; lipids-Membrane structure, energy storage, insulation, and nucleic acids-Information storage and transfer.
What does the protein structure of a virus have to do with the attachment to host cells?
The protein structure of a virus typically includes specific proteins on its outer surface that help it attach to receptors on host cells. This attachment is crucial for the virus to gain entry into the host cell, infect it, and replicate. The binding specificity between viral proteins and host cell receptors is a key determinant of the virus's ability to infect specific cell types.
What kind of cell detects a stimulus?
Sensory cells detect external stimuli such as light, sound, touch, taste, and smell. These cells are specialized in converting the energy from these stimuli into electrical signals that can be interpreted by the brain.
What is the the lower brain that controls and coordinates fine motor movement?
The cerebellum is the lower brain structure responsible for controlling and coordinating fine motor movements. It helps to maintain posture, balance, and smooth execution of voluntary movements.
What do membrane proteins do in the context of cellular function and structure?
Membrane proteins play crucial roles in cellular function and structure by facilitating the transport of molecules across cell membranes, serving as receptors for signaling molecules, and helping to maintain the integrity and stability of the cell membrane.
Which is the first structure stimulated in a reflex arc?
Sensory receptors.
What structure contains hair cells receptive to changes in dynamic equilibrium?
The structure that contains hair cells receptive to changes in dynamic equilibrium is the semicircular canals in the inner ear. These canals are responsible for detecting rotational movements and maintaining balance.
Three movements is a typical formal structure for what baroque?
Three movements is a typical formal structure for a baroque Concerto Grosso.
What structure in the cochlea houses the sound receptors?
The structure in the cochlea that houses the sound receptors is called the organ of Corti. It contains hair cells that are responsible for converting sound vibrations into electrical signals that can be interpreted by the brain.
What are the specialized structure in the cell membrane that are involved in communication?
Receptors and receptor proteins
What structure of the inner ear would be activated by a somersault?
The semicircular canals in the inner ear would be activated by a somersault. These canals are responsible for detecting rotational movements and changes in head position, which helps maintain balance and orientation in space.
How many different kinds of receptors are there for acetylcholine?
There are two main types of receptors for acetylcholine: muscarinic receptors, which are G-protein coupled receptors, and nicotinic receptors, which are ligand-gated ion channels. Each type of receptor is further classified into different subtypes based on their structure and function.
What is the structure composing the internal ear?
The semicircular canals, the vestibule, and the cochlea, which are subdivisions of the bony labyrinth. Semicircular canals and the vestibule contain receptors for equilibrium and the cochlea contains receptors for hearing.
The structure that actually contains the hearing receptors is?
The cochlea is the structure that actually contains the hearing receptors in the inner ear. It is a spiral-shaped organ filled with fluid and lined with tiny hair cells that detect sound vibrations and help transmit auditory information to the brain.
The structure in the hindbrain that controls certain reflexes and coordinates the body's movements is the?
cerebellum.
What type of structure would a hormone's target posses that other non-target organs would not?
Receptors for that hormone
Does the sound go through the semicircular canals?
No, the semicircular canals of the inner ear are responsible for detecting changes in head position and rotational movements, which help with balance and spatial orientation. Sound is detected by the cochlea, a spiral-shaped structure in the inner ear, which converts sound waves into electrical signals that are sent to the brain for interpretation.
