How do cells release <br> Energy in the process of cellular respiration
White raven [17]

Answer:

Explanation:

There are two types of respiration:

1. Aerobic respiration  

2. Anaerobic respiration

Aerobic respiration

It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.

Glucose + oxygen → carbon dioxide + water + 38ATP

Anaerobic Respiration

It is the breakdown of glucose molecule in the absence of oxygen and produce small amount of energy. Alcohol or lactic acid and carbon dioxide are also produced as byproducts.  

Glucose→ lactic acid/alcohol + 2ATP + carbon dioxide

This process use respiratory electron transport chain as electron acceptor instead of oxygen. It is mostly occur in prokaryotes. Its main advantage is that it produce energy (ATP) very quickly as compared to aerobic respiration

Which of the following statements is correct?
Keith_Richards [23]

Answer:

The statement that is correct is that all cells have the same genes, but different genes are active in different cells.

Explanation:

Differentiation or specialization is a function that cells possess and is what allows them to have different types of cells and tissues.

Cell differentiation depends on genetic regulation, a mechanism that determines the specific genes that are expressed in a cell or tissue type.

All cells contain the same DNA, which is organized into chromosomes and contain the genes that determine specific characteristics. <u>There is cell differentiation because some genes can be expressed and others are suppressed, all due to genetic regulation</u>.

The other choices are wrong because:

  • <em>The eyes look different from the liver, because they have the same genes, but only some are expressed. </em>
  • <em>Differentiated cells and tissues do not lose their genes. </em>
  • <em>All cells have DNA.</em>

Use the drop-down menus to answer the questions about genetic recombination. involves the transfer of genetic material from one
Tresset [83]

The right matches are:

• Involves the transfer of genetic material from one bacteria to another ==> Genetic recombination (all 3).

• Involves scraps of genetic material ==> Transformation.

• Uses a virus to transmit genetic material ==> Transduction.

• Uses a pilus to transmit genetic information ==> Conjugation.

• Introduces new genetic material to a bacterium ==> Genetic recombination (all 3).

In molecular biology the term genetic recombination is often used as a synonym for DNA recombination, that is, the processes by which one DNA (or RNA) molecule is cut off, then joined to another.

There are three possible mechanisms in the bacterium: bacterial conjugation, bacterial transformation and transduction.

What site is commonly used to feel a pulse? subclavian artery in the neck aorta in the chest internal jugular vein in the neck r
Nutka1998 [239]

The commonly used site to feel a pulse is radial artery on the wrist, the point where radial artery approaches the wrist present at the middle of wrist.

When we placed our fingers in the middle of wrist, we can feel the pulse wave. That is  72 beats per minutes. The radial artery is the site of insertion of the arterial line, for monitoring the blood pressure. It is selected because it is accessible due to the low incidence of the complications such as thrombosis.

The pressure of the blood is always high in the arteries comparative to the veins, usually arteries are present deep in the body, the radial artery in only artery that approaches the skin. Hence, it is used to monitoring the pulses.
