The yellow box represents a cell with a semi-permeable membrane. The small, blue dots represent molecules of water, and the larg

Snezhnost [94]

The answer would be osmosis

Osmosis is the movement of water caused by the difference in osmotic pressure. The salt or any solute that hydrophilic will attract water. But since it cannot move/diffuse pass the membrane, it is the water that will move to the solute. This will cause the volume of the box with more solute/salt increases.

Which enzyme(s) involved in fatty acid synthesis utilize ATP? Select all that apply.

GREYUIT [131]

Answer:

a. Acetyl CoA carboxylase

Explanation:

Much of the fatty acids used by the body is supplied by the diet, excessive amounts of carbohydrates and protein obtained from the diet can be converted to fatty acids and stored as triglycerides. Fatty acid synthesis occurs mainly in the liver and mammary glands, and to a lesser extent in adipose tissue and kidney, the process incorporates acetyl CoA carbons into the forming fatty acid chain using ATP and NADPH.

The acetyl portion of acetyl CoA is transported to cytosol as citrate, produced by condensation of oxaloacetate and acetyl CoA, the first reaction of the citric acid cycle, this occurs when the concentration of mitochondrial citrate is high, observed when there is a high concentration of ATP and isocitrate dehydrogenase is inhibited. The increase of citrate and ATP favors the synthesis of fatty acids, since this pathway needs both. Acetyl CoA should be converted to malonyl CoA. Carboxylation is catalyzed by acetyl CoA carboxylase and requires ATP, this reaction is the regulated step in fatty acid synthesis: it is inactivated by products, malonyl CoA and palmitoyl CoA, and activated by citrate, another regulatory mechanism is reversible phosphorylation of enzyme, which makes it inactive due to the presence of adrenaline / glucagon

4. A single-celled organism that a student observed under a microscope is shown below.

Katyanochek1 [597]

Explanation:

D. The organism is eukaryotic because it has membrane-bound organelles.

Cells are the basic microscopic units of all organisms. There are two cell types, Prokaryotes and Eukaryotes.

Prokaryotic ( meaning pro: before and Karyon: for kernel/nut) describes organisms which don’t have a cell nucleus or other organelles surrounded by membranes. Eukaryotic (eu meaning true), are organisms with a cell nucleus and several other organelles surrounded by membranes. Example prokaryotes do not contain: nuclei , Golgi apparatus, chloroplasts, mitochondria

Both may contain a cell wall (seen in eukaryotic fungi and plant cells)

Arranged in a phospholipid bilayer, the membrane is semi-permeable; allowing entry into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds. The hydrophilic heads of the bilayer are attracted to water while their water-repellent hydrophobic tails face towards each other- allowing molecules of water and hydrophilic molecules to move across the membrane along the concentration gradient.

Their structural components (i.e. their makeup) determine their function (what they do) . For instance, photosynthesizing cells in algae and plants have structures called chloroplasts. These contain chlorophyll, a specialized compound which facilitates the conversion of light energy to energy stored in carbohydrates. In specific cell types, collected proteins may function as a unit called an organelle. Some organelles are bound by membranes like those that make up the external structure of the cell, with varying compositions of phospholipids and proteins. These are advantageous, as they:

may increase metabolic reaction efficiency; they allow cells to concentrates smaller fractions of enzymes and solutes
separate proteins and molecules that me harm the cell by parceling them into membrane-bound organelles for example, proteaseas bound within lysosomes can break down many structural proteins
