What four products of macronutrient digestion are used in cellular respiration?
carbohydrates are absorbed as , lipids are absorbed as and and proteins are absorbed as

Carbohydrates are absorbed as monosachharides , lipids are absorbed as free fatty acid chains and monoglycerides, and proteins are absorbed as amino acids.

Small intestine is the main site of absorption in human beings. The macro-molecules are digested or breakdown into their simpler constituents before absorption.

Complex carbohydrates are digested with the help of enzymes salivary amylase (mouth), pancreatic amylase, and intestinal enzymes (like maltase, sucrase, lactase et cetera) into their respective monosachharides (such as glucose, fructose). These are then absorbed with the help of micro-villi.

Proteins are first digested into smaller peptides in the stomach with the help of pepsin. These peptides are then digested to dipeptides in the small intestine with the help of pancreatic enzymes like trypsin, chymotrypsin, and carboxypeptidase. These dipeptides are then digested to their respective amino acids with the help of intestinal juices. The amino acids are then absorbed with the help of micro-villi of small intestine.

In small intestine, fats are first emulsified into the small micelles with the help of bile. Pancreatic lipase then convert fats into diglycerides and monoglycerides. Finally, intestinal juices convert diglycerides into free fatty acids and monoglycerides.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands

answer: national resource conservation services

national resource conservation services is the us. based approach that provides technical and financial assistance for natural resource management. nrcs society in conservation of resources by involving in activities like farmland protection, flood prevention, watershed protection, urban conservation, conserves economic and environmental conditions. it conducts soil surveys and implements the policy of natural resources management on the society.
