Multiple Choice
Do typical animal cells contain mitochondria, and what is the primary function of these organelles?
A
Yes; they generate ATP primarily through oxidative phosphorylation during cellular respiration.
B
No; animal cells rely on chloroplasts to generate ATP through photosynthesis.
C
No; animal cells produce ATP only in the nucleus using DNA replication enzymes.
D
Yes; they are the main site of protein synthesis via ribosomes attached to the rough endoplasmic reticulum.
Verified step by step guidance1
Step 1: Understand the question is asking whether typical animal cells contain mitochondria and what their primary function is.
Step 2: Recall that mitochondria are membrane-bound organelles found in most eukaryotic cells, including animal cells.
Step 3: Recognize that mitochondria are known as the 'powerhouses' of the cell because they generate ATP, the cell's main energy currency.
Step 4: Remember that mitochondria produce ATP primarily through a process called oxidative phosphorylation, which is part of cellular respiration.
Step 5: Eliminate incorrect options by noting that animal cells do not have chloroplasts (which are found in plant cells for photosynthesis), ATP is not produced in the nucleus, and protein synthesis occurs at ribosomes, not mitochondria.
