Which cellular organelle contains enzymes that are necessary for intracellular digestion?


Which of the following is an organelle that carries high concentration of digestive enzymes?

The lysosome is the recycling plant of the cell that does intracellular digestion. It breaks down materials brought into the cell (such as nutrients) during endocytosis, recycles old organelles during autophagocytosis, and kills bacteria during phagocytosis in immune cells.

Which two cellular structures are responsible for protein synthesis?

Ribosomes, large complexes of protein and ribonucleic acid (RNA), are the cellular organelles responsible for protein synthesis. They receive their “orders” for protein synthesis from the nucleus where the DNA is transcribed into messenger RNA (mRNA).

How does the mitochondria help in protein synthesis?

Mitochondria use proteins to break down sugars and produce cellular energy in the form of ATP. No matter where mitochondrial proteins are made, they are synthesized on ribosomes that translate messenger RNA into the amino acids that form the protein chain.

What is the role of ATP synthase in cellular metabolism?

ATP synthase is an enzyme that directly generates adenosine triphosphate (ATP) during the process of cellular respiration. ATP synthase forms ATP from adenosine diphosphate (ADP) and an inorganic phosphate (Pi) through oxidative phosphorylation, which is a process in which enzymes oxidize nutrients to form ATP.

What process does the cell go into when there is a low oxygen environment?

When Oxygen is not available, the cell is forced to produce energy (=ATP) through ANAEROBIC processes, that produce much less energy (about 15 times less), than AEROBIC processes. The electron transport chain (ETC) allows the cell to produce energy (ATP) by creating a proton gradient across the mitochondrial membrane.

What is cellular respiration easy?

: any of various energy-yielding oxidative reactions in living matter that typically involve transfer of oxygen and production of carbon dioxide and water as end products Cellular respiration is a series of reactions, occurring under aerobic conditions, during which large amounts of ATP are produced.—

What are examples of cellular respiration?

Types of Cellular Respiration. Cellular respiration can be written as chemical equations. Below are examples of aerobic respiration and anaerobic cellular respiration: lactic acid fermentation and alcoholic fermentation.

Which is a waste product of cells?

Metabolic wastes (carbon dioxide, water, oxygen, and nitrogenous compounds) diffuse through the cell membranes of these unicellular organisms into the outside environment.
