When an animal's stomach contains enzymes that break down food into smaller molecules that the animal's cells can useenzymes perform this function by?
Enzymes in an animal's stomach break down food into smaller molecules by speeding up chemical reactions. They interact with specific substrates in the food molecules to produce smaller, more easily absorbed molecules that can nourish the animal's cells. This process allows the animal to obtain energy and essential nutrients from the food it consumes.
What links animal cells in a leakproof sheet?
Tight junctions are cell junctions that link animal cells tightly together to form a leakproof sheet. These junctions act as barriers that prevent the passage of molecules between cells, ensuring that substances cannot easily pass between them. Tight junctions are crucial for maintaining the integrity and function of tissues in multicellular organisms.
Which cell in the animal cell correspond the cell part or organelle that contain The genetic material DNA?
In animal cells, the organelle that contains genetic material DNA is the nucleus. The nucleus serves as the control center of the cell, housing the cell's chromosomes, which are made up of DNA. It is surrounded by a double membrane called the nuclear envelope, which regulates the passage of ions, molecules, and RNA between the nucleus and the cytoplasm.
What specific structures and or characteristics make biological membranes differentially permeable?
The phospholipids let small and hydrophobic molecules through, this is called passive transport and concerns O2 and H2O. Since that's not all a cell needs, it builds special transporter proteins between the phospholipids to let hydrophilic and big molecules pass. This transport process is driven by concentration difference or active by ATP-cost and brings glucose and the like into the cell.
Which intercellular junction allows for the rapid movement of small molecules or ions to flow from one animal cell to the next?
Gap junctions are the intercellular junctions that facilitate the rapid movement of small molecules or ions between adjacent animal cells. These specialized structures consist of protein channels called connexons that connect the cytoplasm of one cell to that of another, allowing for direct communication and coordination of cellular activities. This connectivity is crucial for processes such as electrical signaling in cardiac and smooth muscle tissues.
What is the purpose of a Gap junction?
A gap junction enables connections between two different animal cells. It allows ions and molecules to pass between the cells freely and helps the organism to continue to exist.

What Controls the passage of substances into and out of a animal cell?
The cell membrane, made up of phospholipids and proteins, controls the passage of substances into and out of animal cells. Selective permeability allows for the regulation of what molecules can enter and leave the cell, maintaining internal conditions necessary for proper cell function. Transport proteins, such as channels and carriers, play a key role in facilitating the movement of specific molecules across the cell membrane.

What is Nuclear Pore in animal cell?
Nuclear pores are large protein complexes that span the nuclear envelope, which surrounds the nucleus in animal cells. These pores regulate the passage of molecules such as proteins and RNA between the nucleus and the cytoplasm, allowing for communication and transportation essential for cell function.
Protein channels that provide passage for hormones and nutrients between animal cells are termed?
gap junctions

Tight junctions are crucial for maintaining the integrity and function of tissues in multicellular organisms.
What is the receiving department of an animal or plant cell called?
The receiving department of an animal cell is called the plasma membrane, while in a plant cell it is called the cell wall. These structures act as boundaries that regulate the passage of molecules in and out of the cell.
What is the different between animal and plant starch?
Animals do not store glucose in starch molecules, but rather in glycogen molecules. Starch molecules have infrequent branching of glucose chains and as such are not readily broken down into glucose monomers by the enzymes that catalyze the reaction. Glycogen molecules follow the same basic structure as starch molecules, but instead have more branching and consequently are broken down easier. This allows for quicker "burst" energy and is better suited to animals' mobility.
Which plant structure is most like gap junctions in animal cells?
Plasmodesmata in plant cells are most similar to gap junctions in animal cells. Plasmodesmata are channels that allow for the direct exchange of molecules between plant cells, similar to how gap junctions allow for communication and transport of molecules between animal cells.
Connection between animal cells that creates impermeable layer?
Tight junctions between animal cells create an impermeable barrier that prevents the passage of molecules between cells. These junctions seal the space between cells, controlling the movement of substances. Tight junctions are important in maintaining tissue integrity and barrier function in organs such as the intestines and blood-brain barrier.
What is a crop on an insect?
The crop of an animal or insect comes between the mouth and stomach and allows them to store food.
