What is the site for ATP synthesis in bacterial cells? In bacterial cells, ATP synthesis occurs at the cell (plasma) membrane, since bacteria lack mitochondria. What process do mitochondria use to generate ATP for the cell? Mitochondria use cellular respiration to break down food sources like sugars and lipids to generate ATP. What are the two membranes of the mitochondria called? The two membranes are called the outer membrane and the folded inner membrane. What is the name of the folds found in the inner mitochondrial membrane? The folds in the inner mitochondrial membrane are called cristae. What does the mitochondrial matrix contain? The mitochondrial matrix contains enzymes, ribosomes, and mitochondrial DNA. What is the main function of chloroplasts in plant cells? Chloroplasts are responsible for photosynthesis, converting sunlight, carbon dioxide, and water into glucose and oxygen. What are thylakoids and where are they found? Thylakoids are interconnected, pancake-shaped sacs found inside chloroplasts. What is the stroma in a chloroplast? The stroma is the innermost region of the chloroplast, containing enzymes, ribosomes, and chloroplast DNA. What is the difference between the membranes of mitochondria and chloroplasts? Mitochondria have a folded inner membrane with cristae, while chloroplast membranes do not have folds or cristae. What are grana in chloroplasts? Grana are stacks of thylakoids found within the chloroplast.
