2d Flashcards
What are the primary functions of mitochondria?
Sites of cellular respiration, converting chemical energy into ATP.
Describe the structure of mitochondria.
Smooth outer membrane, inner membrane folded into cristae, with compartments for intermembrane space and mitochondrial matrix.
What is the role of chloroplasts in cells?
Sites of photosynthesis in plants and algae
What are the main functions of the cytoskeleton?
Provides support, facilitates motility, and regulates biochemical activities.
What key structures are found in chloroplasts?
Outer and inner membranes, thylakoids, and stroma.
What do peroxisomes do?
Carry out oxidative reactions, produce hydrogen peroxide, and convert it to water.
What are microtubules, and what functions do they serve?
Thickest fibers of the cytoskeleton, guiding organelle movement and separating chromosomes during cell division.
What is the role of microfilaments in muscle contraction?
Actin filaments interact with myosin to generate movement
What is cytoplasmic streaming?
A circular flow of cytoplasm that speeds the distribution of materials within the cell.
