Answer: Peroxisome
Explanation:
A peroxisome is a membrane-bound organelle usually found in the cytoplasm of almost all eukaryotic cells. It is an oxidative organelle.
Eukaryotes are comprised of one or more cells that contain peroxisomes. The organelles were first discovered by the Belgian scientist Christian de Duve, who was same person that discovered lysosomes.
Peroxisomes contain a variety of enzymes, which primarily function together to get rid of toxic substances in the cell, and in particular, hydrogen peroxide which a common byproduct of cellular metabolism. These organelles contain enzymes that convert the hydrogen peroxide to water, making it remain safe in order to be released back into the cell. Some types of peroxisomes, such as those in liver cells, detoxify alcohol and several other harmful compounds by transferring hydrogen from the poisons to molecules of oxygen (known as oxidation). Other perixosomes are more important for their ability to initiate the production of phospholipids, which are typically used in the formation of membranes.
It might be carbon, I think this because of the pencil having graphite which is made of carbon.
Answer:
The correct answer is 4. reducing molecule
Explanation:
NADH is a coenzyme that plays an important role in making ATP during cellular respiration or oxidative phosphorylation. It stays in two forms in the cell which is NADH which is it's reduced form and NAD+ which is it's oxidized form.
So as NADH is a reduced form and it acts as the electron donor and feed electron in the electron transport chain during oxidative phosphorylation. After donating electron it gets converts into it's oxidized form which is NAD+. Therefore NADH acts as reducing molecule in cellular respiration.
Answer: The gymnosperm life cycle has a dominant sporophyte generation. Both gametophytes and the next generation's new sporophytes develop on the sporophyte parent plant. ... Each female gametophyte produces an egg inside an ovule. Pollination occurs when pollen is transferred from a male to female cone.
Explanation:
Answer: Option A
The blood is the least that can harbour commensal microbes.
Explanation:
Commensal microbes are microbes that form a relationship with an organism in which one benefits and neither is hurt. These bacteria are necessary for a healthy and developed immune system. They are part of the microplora in the mouth. Commensal bacteria are least in the blood because the blood is a sterile environment and is not conducive for their habitation. The immune response of the blood to the bacteria can cause septic shook which can lead to death.
