A doctor studies cells from the spinal Fluid from a very sick baby. After analyzing the lipid content in the cells, the doctor finds a very high concentration of a fatty

toxic substance called GM2 ganglioside. This toxic substance is normally broken down in

healthy cells. She suspects that this baby has a genetic disorder affecting one

particular organelle involved in recycling and breaking down larger molecules

2 Which organelle or cellular structure might not be able to perform its job and have defective proteins as a result

of this genetic disorder? Explain your answer below.

Lysosomes

Explanation:

Lysosomes are membrane bound organelles that contain digestive enzymes that are used to break down large molecules such as carbohydrate, protein and lipids. They also contain degradative enzymes that are used to degrade dead cells.

The genetic disorder must have affected the development of lysosomes (which makes it have defective enzymes/proteins) in the baby's cells which is the reason she is unable to break down the fatty toxic substance.

NOTE: Most enzymes are proteins and were used interchangeably in the second part of the question

satellites are frequently used to make observations of the orbit on earth

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
