Is a eukaryotic cell has organelles surrounded by membranes true or false?
true
Proteins are assembled in the nucleus of a cell?
false
Crossing the international date line changes the date not the hour is this true or false?
False. Crossing the International Date Line changes both the date and the hour. When crossing from east to west, you move forward a day, and when crossing from west to east, you move back a day.
Does the stroma separate the inner and outer membranes of the mitochondria?
No, the stroma is found in chloroplasts, not mitochondria. In mitochondria, the inner and outer membranes are separated by the intermembrane space.
Is this true or false Four major types of macromolecules are proteins carbohydrates lipids and glycerol?
False. Glycerol is not a macromolecule itself, but a component of lipids. The four major types of macromolecules are proteins, carbohydrates, lipids, and nucleic acids.
Is this question true or false most polar molecules cannot cross cell membranes without the help of certain proteins?
true
The dark reactions occur within the thylakoid membranes true or false?
False. False.
Is the following sentence true or false Both chloroplasts and mitochondria are enclosed by two envelope membranes?
True. Both chloroplasts and mitochondria have a double-membrane envelope that surrounds their organelle structures.
Do proteins at the inner surface of the plasma membrane attach to the membrane to the cells support the structure?
Yes, proteins at the inner surface of the plasma membrane can attach to the cytoskeleton of the cell, providing support and helping to maintain the structure of the membrane. These membrane-associated proteins interact with the cytoskeleton to anchor the membrane in place and facilitate cell shape and movement.
Dark reactions occur within the thylakoid membranes?
It's a true and false question, the answer is: False
Are membranes selectively permeable if they allow only certain substances to move across them?
False.
Is fats help maintain your cell membranes true or false?
True. Fats help maintain the flexibility and integrity of cell membranes, allowing them to function properly in controlling what enters and exits the cell. Essential fatty acids, such as omega-3 and omega-6, are especially important for this function.
Is the 20 different polysaccharides used to make proteins true or false?
False. Polysaccharides are complex carbohydrates made of sugar molecules bonded together. Proteins are made from amino acids, not polysaccharides.
Is a eukaryotic cell has organelles surrounded by membranes true or false?
true
Proteins are assembled in the nucleus of the cell?
False!!
Proteins are assembled in the nucleus of a cell?
false
Crossing the international date line changes the date not the hour is this true or false?
False. Crossing the International Date Line changes both the date and the hour. When crossing from east to west, you move forward a day, and when crossing from west to east, you move back a day.
