Robert Hooke is the first person to observe cells as microscopic structures.

He was of British descent and, fun fact, he discovered cells by looking at a sliver of cork under a microscope lens (although the 'fun fact' is heavily simplified).

Use the diagram to answer the question below. Which sequence lists the cell images in chronological order for mitosis
kifflom [539]

Mitosis goes in the order of PMAT, or Prophase, Metaphase, Anaphase, and Telophase.


Prophase is when the nuclear envelope breaks down and the chromosomes are visible. Metaphase is when the chromosomes line up in the middle. Anaphase is when the spindle fibers pull the centromeres apart. Telophase is when the chromosomes go to the opposite sides and the nuclear envelope reappears.

Multiple Select Question

The TRUE statements are 'proteins often have more than one transmembrane domain'; 'they are regions of a transmembrane protein that actually pass through the lipid bilayer' and 'they are usually shaped like alpha-helices'.

A transmembrane domain is a membrane-spanning region within a protein. The transmembrane domains are hydrophobic regions that can be inserted into the cell membrane.

The transmembrane domains are usually shaped like alpha-helices.

This secondary structure (alpha-helices) causes the amino acid R-groups to project radially, thereby these side chains can interact with each other.

Proteins need only a single transmembrane domain to be anchored to the membrane, but they often have more than one.

For example, Acyl-coenzyme A cholesterol acyltransferases 1 and 2 (ACAT1 and ACAT2)  have multiple transmembrane domains.

The transmembrane domains are regions of a transmembrane protein that actually pass through the lipid bilayer.

These domains contain amino acids with hydrophobic R-groups that pass through the membrane and interact with the hydrophobic tails of the fatty acid chains present in the lipid bilayer.

The transmembrane domains anchor transmembrane proteins to the lipid bilayer.

The interactions between amino acids of the transmembrane domains and fatty acids in the lipid bilayer help to anchor transmembrane proteins and stabilize the cell membrane.

I’m stage 2 of photosynthesis NADP becomes NADPH why?
nignag [31]
NADPH is a reduced form of NADP+. The latter features an extra hydrogen ion in its chemical structure. When NADP+ transforms into NADPH, the other hydrogen ion  is released as part of the reaction while the other hydrogen ion becomes a part of the NADPH structure.
