Which is true about ribosomes?

• Ribosomes synthesize proteins

• Ribosomes synthesize catalysts

• Ribosomes synthesize antibodies

• Ribosomes synthesize all of these

The rough ER is involved in

• protein digestion

• carbohydrate synthesis

• DNA synthesis

• protein synthesis with ribosomes

The smooth ER is involved in

• protein synthesis

• lipid synthesis

• carbohydrate synthesis

• DNA synthesis

Cisternae are flat layers of membranes that make up the

• mitochondria

• nucleus

• chloroplast

• golgi apparatus

The primary site of respiration and adenosine triphosphate synthesis is the

• mitochondria

• nucleus

• lysosomes

• ribosomes

Intracellular digestion occurs in the

• ribosomes

• mitochondria

• lysosomes

• golgi apparatus

Vacuoles

• are only found in plants

• are only found in animals

• are found in both plants and animals

• are found only in bacteria

Chloroplasts are necessary for

• photosynthesis to occur in plants

• photosynthesis to occur in animals

• photosynthesis to be inhibited

• photosynthesis to create ATP

What is typically true about the surface area to volume ratio of a cell?

• The higher the SA:V ratio, the faster diffusion occurs

• Shape can influence the SA:V ratio

• Temperature can influence the SA:V ratio

• Concentration can influence the SA:V ratio

What is typically true about diffusion rate?

• Temperature can affect SA:V

• Shape can affect SA:V

• Shape and temperature can affect diffusion rates

• Volume of a cell does not affect diffusion rates
