What is the function of the structures at D quizlet?
What is the function of the structures at D? Nuclear pores allow ribosomes, mRNA, and many other large molecules to pass but contain the DNA within the nucleus.
What is the function of the indicated protein?
What is the function of the indicated protein? DNA forms chromatin by wrapping around nucleosomes formed by histone proteins and therefore becomes more condensed. Drag the appropriate labels to their respective targets.
Which mechanism requires energy input by the cell in the form of ATP hydrolysis?
active transport
During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.
What does passive membrane transport processes include?
Passive membrane transport processes include simple diffusion, facilitated diffusion and osmosis.
Which process is indicated by C?
What process is indicated by C? exocytosis of secreted proteins. The event indicated by C includes the fusion of a secretory vesiclel with the plasma membrane and the subsequent release of the vesicle contents to the extracelluar space.
What is trypsin and its function?
Trypsin is an enzyme that helps us digest protein. In the small intestine, trypsin breaks down proteins, continuing the process of digestion that began in the stomach. Trypsin is produced by the pancreas in an inactive form called trypsinogen.
What are three functions of proteins?
Here are 9 important functions of protein in your body.
- Growth and Maintenance. Share on Pinterest.
- Causes Biochemical Reactions.
- Acts as a Messenger.
- Provides Structure.
- Maintains Proper pH.
- Balances Fluids.
- Bolsters Immune Health.
- Transports and Stores Nutrients.
What are the 4 types of membrane transport?
Basic types of membrane transport, simple passive diffusion, facilitated diffusion (by channels and carriers), and active transport.
How is the cell cycle divided into two parts?
Part B: mRNA carries the code for a polypeptide’s sequence of amino acids. Part C: tRNA carries amino acids to the ribosome. The cell cycle is divided into two main parts: interphase and cell division.
Which is allowed for communication and passage of small molecules between adjacent cells?
Which of the following allows for communication and the passage of small molecules between adjacent cells? Nice work! You just studied 32 terms! Now up your study game with Learn mode. What is the force driving all of these transport mechanisms?
Which is responsible for performing this function in normal cells?
Which organelle is responsible for performing this function in normal cells? Lysosomes serve as the cell’s garbage disposers, breaking down unwanted materials. Which of the following is not a passive process?
Which is the following is characteristic of cilia?
They contain powerful enzymes called acid hydrolases. Which of the following is characteristic of cilia? They are whiplike, motile cellular extensions that occur in large numbers on the exposed surfaces of certain cells. Lysosomes perform digestive functions within a cell.
