Which organelle is responsible for producing lysosomes?
Lysosomes originate by budding off from the membrane of the trans-Golgi network, a region of the Golgi complex responsible for sorting newly synthesized proteins, which may be designated for use in lysosomes, endosomes, or the plasma membrane.
What is the function of the intermembrane compartment of the mitochondria?
the intermembrane space: holds protons that are pumped out of the matrix during electron transport, the inner mitochondrial membrane: organizes the electron transport chain and holds ATP synthase, the cristae: expand the surface area of the inner mitochondrial membrane, enhancing its ability to produce ATP, and.
What is the main function of cristae in mitochondria quizlet?
Mitochondrial cristae are folds of the mitochondrial inner membrane that provide an increase in the surface area. This allows a greater space for processes that happen across this membrane. The electron transport chain and chemiosmosis are the processes which help produce ATP in the final steps of cellular respiration.
What is the purpose of the intermembrane space in chloroplast?
The intermembrane space is a compartment of very small volume since the outer and inner membranes are in very close proximity. Only a relatively small number of components of the intermembrane space are known, most of which are required for mitochondrial biogenesis or have a function in energy metabolism.
What is the function of the gallbladder?
The gallbladder stores and concentrates bile between meals. Gallbladder motor function is regulated by bile acids via the membrane bile acid receptor, TGR5, and by neurohormonal signals linked to digestion, for example, cholecystokinin and FGF15/19 intestinal hormones, which trigger gallbladder emptying and refilling, respectively.
What is the main function of plastids?
Plastids are the largest cell organelle in plants. These are responsible for photosynthesis and act as storage devices for starch and helps in the synthesis of various molecules like fatty acids and terpene. Source: NCERT Text Book Types Of Plastids And Functions Of Plastids
What type of tissue is the gallbladder made of?
The muscularis— a layer of smooth muscle tissue that enables the gallbladder to contract to release bile into the bile duct. The perimuscular— a fibrous connective tissue layer, that surrounds the muscularis. The serosa— a smooth membrane that forms the outer covering of the gallbladder.
What stimulates the release of bile from the gallbladder?
Note that 50% of the bile that flows through the common bile duct is stored in the gallbladder. After food is eaten, a hormone called cholecystokinin is secreted; this stimulates the release of bile, and the bile begins breaking down fats in the digestive system.
