What is the process of recycling mitochondria?
Mitophagy is a process for clearing damaged mitochondria, and a critical component of normal mitochondrial quality control (35).
Why do mitochondria need lysosomes?
Mitochondria and lysosomes are essential for cellular metabolism as major contributors of chemical energy and building blocks. It is therefore pivotal for cellular function to coordinate the metabolic roles of mitochondria and lysosomes.
Why does a decrease in lysosome production lead to decline in mitochondrial activity?
Which of the following claims is scientifically accurate and consistent with an observation that a decrease in lysosome production within a cell leads to a decline in mitochondrial activity? Fewer lysosomes will be available to break down macromolecules to provide the necessary nutrients for cellular respiration.
Do lysosomes break down macromolecules?
Lysosomes break down macromolecules into their constituent parts, which are then recycled. These membrane-bound organelles contain a variety of enzymes called hydrolases that can digest proteins, nucleic acids, lipids, and complex sugars. The lumen of a lysosome is more acidic than the cytoplasm.
Why lysosomes are called as waste disposal system of the cell?
Lysosomes are commonly referred to as the “garbage disposal” structure of our body. Since lysosomes are digestion machines, they go to work when the cell absorbs or eats some food. Once the material is inside the cell, the lysosomes attach and release their enzymes.
What is transported in exocytosis?
Exocytosis (/ˌɛksoʊsaɪˈtoʊsɪs/) is a form of active transport and bulk transport in which a cell transports molecules (e.g., neurotransmitters and proteins) out of the cell (exo- + cytosis). As an active transport mechanism, exocytosis requires the use of energy to transport material.
What is the mitochondria function?
Mitochondria are membrane bound organelles present in almost all eukaryotic cells. Responsible for orchestrating cellular energy production, they are central to the maintenance of life and the gatekeepers of cell death.
