The percentage range of an adult's kilocalorie that is recommended as the maximum to be from fat is between 20-35% of kcal from fat. Fats and oils are part of a healthful diet, however the type of fat makes a difference to heart health and the total amount of fat consumed is important. Fat contains about 9 kilocalorie per gram. Fats are classified as saturated, monosaturated, or polysaturated based on the type of chemical bonds in their fatty acids. The recommended fat intake is between 20 to 30 percent of calories for adults, 30 to 35 percent of calories for children 2 to 3 years and 25 to 35 percent for adolescents 4 to 18 years of age.
False. The number of trees is more than the number of trees cut down.
-Homeostasis:maintains stable internal conditions
-Metabolism:cellular respiration
-Growth:biosynthesis
-Made of cells:mitosis and differentiation
-Responds to changes in environment:plant bending towards light
Answer:Since DNA is double-stranded, two different RNA molecules could in principle be transcribed from any gene, using each of the two DNA strands as a template.
Explanation:During transcription, the DNA of a gene serves as a template for complementary base-pairing, and an enzyme called RNA polymerase II catalyzes the formation of a pre-mRNA molecule, which is then processed to form mature mRNA
Answer:
The correct answer will be options
1. Process includes glycolysis.
2. Between 2 and 38 ATP are produced per molecule of glucose input .
3. Much or most of the ATP produced is produced by oxidative phosphorylation.
4. Process involves electron transport and chemiosmosis.
5. End products are CO₂ and H₂O.
6. Process involves the Krebs cycle.
Explanation:
Cellular respiration is the oxidative process which involves the breakdown of food molecules like glucose, amino acids and fats to release heat and energy in the form of ATP.
In the presence of oxygen or aerobic respiration it undergoes four stages: glycolysis, link reaction, Krebs cycle and electron transport chain while in the anaerobic reaction it produces ethanol and carbon dioxide by the process of fermentation.
Each stage produces energy in the form of ATP molecules or co-enzymes NADH OR FADH₂ like glycolysis produces 2 ATP and link reaction, Krebs cycle produces NADH OR FADH₂ in addition to ATP. Each NADH produces 3 ATP while Each FADH₂ produces 2 ATP during electron transport chain. So, ATP molecules are produced between 2 to 38 ATP molecules in each stage with large number during electron transport chain from these co-enzymes.
The waste products produced in the stages of cellular respiration are CO₂ molecules and H₂O which is also known as metabolic water.
