The breakdown of food into molecules small enough to enter the bloodstream is primarily accomplished by the _____.stomach
small intestine
large intestine
liver

Answers

Answer 1
Answer:

Answer:

The correct answer would be a small intestine.

The small intestine is the principal organ of digestion as well as absorption.

Events take place in the small intestine:

  • Intestinal enzymes such as maltase, lactase, sucrase et cetera digest disaccharides to their respective monosaccharides such as glucose, fructose, galactose.
  • Dipeptides are digested to amino acids.
  • Intestinal lipases convert di and triglycerides into fatty acids and glycerols.
  • Lastly, nucleotide and nucleoside are converted their respective sugars and bases.
  • The digested food is then absorbed with the help of diffusion, facilitated diffusion, and active transport.
  • The mucosa layer of small intestine consists of finger-like projections called villi and microvilli.
  • They increase the surface area of the small intestine and help in absorbing the digested food.  
  • They then transport the absorbed materials to the bloodstream through capillaries and lymphatic vessels lying close to their surface.

What are two advantages of glycolysis

Answers

Glycolysis, the initial stage of cellular respiration, offers several advantages essential for cells' energy production and survival. Two significant advantages are Efficiency and Substrate availability.

1. Efficiency: Glycolysis occurs in the cytoplasm and does not require oxygen, making it an anaerobic process suitable for cells in low-oxygen environments.

It rapidly converts glucose into two molecules of pyruvate, producing a small amount of ATP and NADH.

2. Substrate availability: Glycolysis uses glucose, a simple sugar readily available from various sources like carbohydrates.

This flexibility allows cells to obtain energy from different nutrient molecules, ensuring a continuous supply of substrates for energy production even when other energy sources are limited or unavailable.

Glycolysis plays a fundamental role in sustaining cellular energy needs under diverse conditions.

Which organelle packages and distributes proteins that are received from the endoplasmic reticulum?

Answers

Golgi apparatus organelle packages and distributes proteins that are received from the endoplasmic reticulum. So, the correct option is C.

What is Golgi apparatus?

Golgi apparatus is also called Golgi complex, Golgi body or simply Golgi is defined as an organelle found in most eukaryotic cells. It is part of the endomembrane system in the cytoplasm that packages proteins into membrane-bound vesicles inside the cell before the vesicles are sent to their destination.

Golgi apparatus organelle packages and distributes proteins that are received from the endoplasmic reticulum. Its main function is the packaging and secretion of proteins that receive proteins from the endoplasmic reticulum and package them into membrane-bound vesicles, which are then transported to various sites, such as the lysosome, the plasma membrane, or the secretion.

So, the correct option is C.

Small aquatic organisms, such as coral, are the producers of the ocean. true or false

Answers

This statement is true. Small aquative organisms like coral are the producers of the ocean, because they do not to feed upon other organisms to survive and they themselves produce oxygen which is needed in the water.

Cleansing the venipuncture site before collection of blood culture specimens usually involves the use of: isopropyl alcohol and peroxide ethyl alcohol and peroxide isopropyl alcohol and chlorhexidine gluconate ethyl alcohol and chlorophenol

Answers

Answer:

C) isopropyl alcohol and chlorhexidine gluconate

Explanation:

The World Health Organization (WHO) guidelines mandate that the venipuncture site be cleaned with an alcohol swab of 70 percent alcohol.

Document H3-A6 is also recommended by the Clinical and Laboratory Standards Institute (CLSI) that skin disinfection with 70% isopropyl alcohol or ethanol is required before venipuncturing tosterile the skin surface. chlorhexidine gluconate  is a good repacment of isopropyl alcohol, hence used at venipuncture site.

Hence, the correct option is C.
