Kidneys are often compared to filters because they cleanse unwanted waste from both frogs and humans true or false ?
PtichkaEL [24]

"Kidneys are often compared to filters because they cleanse unwanted waste from both frogs and humans" is TRUE.

Answer: Option A

<u>Explanation: </u>

Frogs also have the excretory system with two kidneys and similar to mammals. Its function is to eliminate the nitrogen product from the blood. Frogs make large volumes of dilute urine to wipe out harmful products from the tubules of the kidneys.

Tadpoles and aquatic frogs excrete the nitrogen as ammonia, but most terrestrial adults excrete it mostly as urea which is less threatening substance. A few tree frog species with little water access excrete the still less harmful uric acid.

Drag the correct word from the left into the sentence on the right to complete each sentence. In anabolic reactions that involve
kkurt [141]

Answer:

The correct matches are:

  1. In anabolic reactions that involve the synthesis of a large molecule from smaller precursor molecules, NADH and ATP are consumed when they provide the needed electrons or energy.
  2. In catabolic reactions that involve the breakdown of a molecule into smaller subunits, such as glucose to pyruvate, NADH and ATP are produced.
  3. In the reaction Pyruvate +NADH-Lactate +NAD, pyruvate is being reduced.
  4. In the reaction Pyruvate NADH-Lactate +NAD, NADH is being oxidized.

Explanation:

  • Being involved in synthesis, anabolic reactions require energy in the form of energy storing molecules such as NADH and ATP. Anabolic processes utilize energy produced by the catabolism of complex compounds.
  • Catabolic processes produce energy or energy storing compounds by breaking down complex substances into simpler ones. All steps of cellular respiration are catabolic processes since they generate energy in the form of ATP or energy yielding molecules such as NADH and FADH2.
  • Anaerobic respiration takes place during intense physical activity due to which adequate oxygen does not reach the cells. Insufficient oxygen shuttles the pyruvate molecules produced by glycolysis into the lactic acid pathway that reduces pyruvate into lactic acid.
  • Since, NADH is donating its H+, it is being oxidized to NAD+.

Neko [114]

Answer:

Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products.
