Anna [14]

The importance of conservation of habitats is that habitat conservation protects biodiversity in the region.

<h3>Conservation of habitats</h3>

Habitat can be defined as an environment that is made up of resources that are used by a particular organism.

There are different types of habitat which include:

  • aquatic habitat,

  • terrestrial habitat and

  • arboreal habitat.

These habitats needs to be conserved to maintain biodiversity which is an essential part of global food security.

Which of the following statements correctly describes some aspect of ATP hydrolysis being used to drive the active transport of
saw5 [17]

Answer:

B) This is an example of energy coupling

Explanation:

Energy coupling is a process by which cells carry out thermodynamically unfavorable, endergonic (energy-requiring) reactions to other exergonic (reactions that liberate free energy) reactions.

Reactions which are endergonic do not occur spontaneously as they result in a decrease in entropy and a positive free energy change, ∆G.

Exergonic reactions occur spontaneously as they result in an increase in entropy and have a negative free energy change, ∆G.

For example, the active transport of ions against their concentration gradients in cells is a non-spontaneous endergonic process which is coupled to the hydrolysis of ATP, an exergonic process in other for the reaction to proceed. ATP hydrolysis phosphorylates an amino acid side chain in the transport protein which then drives the forward process of transport of the ion.

Considering the above,

Option A: The hydrolysis of ATP is endergonic, and the active transport is exergonic is false because ATP hydrolysis is exergonic while active transport is endergonic.

Option B: This is an example of energy coupling is true.

Option C: Both ATP hydrolysis and active transport are spontaneous because they result in an increase in entropy of the system is false because only ATP hydrolysis is spontaneous

Option D: Neither ATP hydrolysis nor active transport is spontaneous is false because ATP hydrolysis is spontaneous.

Option E: ATP is acting as a transport protein to facilitate the movement of the ion across the plasma membrane is false because ATP is not a protein, rather it serves to activate the transport protein by phosphorylating it.

Generally, animals cannot digest (hydrolyze) the glycosidic linkages between the glucose molecules in cellulose. how then do cow
Andrei [34K]

Microorganisms in their digestive tracts hydrolyze the cellulose to individual glucose units.

Cellulose- The stable formation of plant cell walls is greatly aided by cellulose, a hard, fibrous, and water-insoluble polysaccharide. The fibrils (bundles of microfibrils) and microfibrils (bundles of polysaccharide) made up of cellulose chains make up the plant cell wall.

Glucose- The primary form of sugar in the blood, glucose serves as the body's cells' principal source of energy. Glucose may be produced by the body from other chemicals or it can be obtained from the meals we eat. The circulation carries glucose to the cells. Insulin is one of many hormones that regulate blood glucose levels.
