What are the distinguishing characteristics of the free living members of sarcodina?

The distinguishing characteristics of the free living members of sarcodina are:

1. These are pseudopods (function in locomotion) which makes it the extentions of protoplasm.

2. These have both a clear ectoplasm and a granualated endoplasm.

3. These have nucleus both food vacuoles and contractile vacuoles.

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
