Summary Introduction
To review:
The significant size difference between mitochondria and chloroplasts.
Introduction:
Chloroplast and mitochondria have evolved from free-living prokaryotes to now host-dependent cell organelles. They share great similarity, especially in terms of generation of energy molecules for the organism. They have their own genetic material and replicate on their own, still many differences distinguish the two organelles from each other:one of them being their size.

QUESTION NO. 1L-Carnitine is synthesized primarily in the liver but also in the kidneys and then transported to other tissues. It is most concentrated in tissues that use fatty acids as their primary fuel, such as skeletal and cardiac muscle. In this regard, L-carnitine plays an important role in energy production by conjugating to fatty acids for transport from the cytosol into the mitochondria. L-carnitine shuttle is an example of
A. ion driven active transport
B. facilitated diffusion
C. simple diffusion
D. ATP driven active transportE. symport
F. antiportQUESTION NO.2 Statements: (1) Glucose is both a hexose and a aldose. (2) There can never be more than three enantiomers for a molecule. (3) All common disaccharides have beta-one-four linkages. Which statements are true?
