Answer:
is equal to the total number of products
Explanation:
Answer:
oxygen is reduced to form water.
Explanation:
Cellular respiration
It is the set of reactions in which the ac. Pyruvic produced by glycolysis is split into CO2 and H2O and 36 ATP are produced. In eukaryotic cells breathing is performed in the mitochondria. It occurs in two stages:
- PIRUVATE OXIDATION
- AC CYCLE TRICARBOXYL
The "problem" with fermentation is that, by using organic molecules as terminal electron acceptors and having to dispose of the resulting product (lactic acid / ethanol) as waste, the potential energy of these compounds is lost.
The alternative solution is to use some non-organic molecule that can accept electrons and thus become a reduced molecule. Oxygen is perfect for this, because after receiving the electrons it combines with two protons, thus becoming the perfect liquid residue for the environment: H2O.
Answer:
d. Epoxy
Explanation:
Adhesion or adhesive properties of a substance is the property that allows bonding of dissimilar materials if necessary. Adhesives may have high cohesive strength or a low cohesive strength.
PVC "glue" is usually a solvent for plastic components and these are different type of PVC glues. They function well on plastics.
HDPE - is known as High-density polyethylene or polyethylene high-density is a thermoplastic polymer in short it is what we know as plastic bags or nylon produced from the monomer ethylene. HDPE is not an adhesive
UHMWPE - is known as Ultra-high-molecular-weight polyethylene (UHMWPE, UHMW) is a subset of the thermoplastic polyethylene. Also known as high-modulus polyethylene, (HMPE). UHMWPE is not an adhesive.
An epoxy adhesive is a copolymer adhesive formed by mixing together a resin and a hardener. There are some special epoxies however don't require a hardener, but are activated by heat instead. Others epoxies hardening strength may degrade in under exposure to ultraviolet light or high heat. Adhesives such as epoxies have many different uses. Epoxy may be used on metal, glass, plastic, rubber, fiberglass and fiberglass-reinforced plastic (FRP).
Bakelite or polyoxybenzylmethylenglycolanhydride isn't an adhesive and it was the first plastic made from synthetic components.
Epoxy however has very strong adhesive properties because of the varieties of substances it can bring to together.
