What are the main differences between prokaryotic and eukaryotic cells?

Prokaryotic cells are simpler and smaller, lack a nucleus, and have circular DNA, while eukaryotic cells are more complex, larger, have a nucleus, and linear DNA.

Prokaryotic cells are multicellular, while eukaryotic cells are unicellular.

Prokaryotic cells have linear DNA and a nucleus, while eukaryotic cells have circular DNA and lack a nucleus.

Prokaryotic cells are larger and more complex, while eukaryotic cells are smaller and simpler.

What are the main differences between plant and animal cells?

Plant cells have cell walls, chloroplasts, and large central vacuoles, while animal cells have centrioles, lysosomes, and cilia or flagella.

Plant cells have ribosomes, endoplasmic reticulum, and Golgi apparatus, while animal cells have cell walls, chloroplasts, and large central vacuoles.

Plant cells have mitochondria, nucleus, and cytoplasm, while animal cells have cell walls, chloroplasts, and large central vacuoles.

Plant cells have centrioles, lysosomes, and cilia or flagella, while animal cells have cell walls, chloroplasts, and large central vacuoles.

Match the components of the cytoskeleton with their function

Helical polymers made up of actin monomers found in different parts of the cytoplasm.

Long, hollow tubes made up of tubulin dimers that help in cell division.

Motor proteins that move along microtubules carrying cargo within the cell.

How do enzymes decrease the amount of activation energy needed to begin breaking bonds?

Enzymes provide an alternative pathway for the reaction to occur, lowering the energy barrier.

Enzymes have no effect on the activation energy of a reaction

Enzymes speed up reactions by increasing the activation energy

Enzymes increase the activation energy required for a reaction

Match the phase of cellular respiration with what happens during it.

This stage takes place in the cytoplasm. Glucose is broken down into 2 pyruvate molecules. Produces 2 ATP and 2 NADH and 2 H2O

This stage occurs in the mitochondrial matrix. Pyruvate is converted into Acetyl CoA. Produces 2 NADH and 2 CO2

This stage occurs in the mitochondrial matrix. Acetyl CoA enters the Krebs cycle. Produces 2 ATP, 6 NADH, 2 FADH2, and 4 CO2

This stage takes place in the mitochondrial matrix. NADH and FADH2 donate electrons to the electron transport chain. Produces 28 ATP and H2O

How does ATP synthase work?

ATP synthase converts ADP and inorganic phosphate into ATP using the energy from a proton gradient.

ATP synthase is not involved in ATP production

ATP synthase uses glucose to produce ATP

ATP synthase breaks down ATP into ADP and inorganic phosphate
