Which of the statements is true of facilitated diffusion?
Substances are transported out of the cell only.
Transport occurs with the help of membrane proteins.
Energy is required for transport of substances.
Substances are transported against their concentration gradient.
What is hypertonic?
No net movement of water
Lose water to extracellular surroundings
Gains water
Sweat, released through ducts to the skin surface, helps to cool the body. The types of cells that produce these compounds have different numbers of specific organelles, depending on their function? Based on their function, you would expect melanocytes in the skin to have a higher than usual number of....
lysosomes
chloroplasts
golgi bodies
ribosomes
The endosymbiont theory is supported by all the following pieces of evidence except the fact that...
mitochondria have circular DNA like prokaryotes
mitochondria use ATP like prokaryotes
chloroplasts have ribosomes like prokaryotes
chloroplasts reproduce through a splitting process like certain prokaryotes
Which of the following best describes how organelles within the endomembrane system function together to transport proteins?
Contiguous extracellular membranes connect each organelle, allowing for proteins to travel through the endomembrane system.
Ribosomes bud off from one organelle and then fuse with others to transport proteins through the endomembrane system.
Vesicles bud off from one organelle and then fuse with others to transport proteins through the endomembrane system.
Contiguous intracellular membranes connect each organelle, allowing proteins to travel through the endomembrane system.
Which of the following are common traits of chloroplasts and mitochondria?
both are surrounded by a single membrane
both have their own DNA
both are found in plant and animal cells.
both synthesize proteins on ribosomes in the rough ER
Large molecules are moved out of the cell by which of the following processes?
endocytosis
exocytosis
vesicles
