Cellular Respiration is important because it converts __glucose________ into usable energy for the body.

Photosynthesis is

important because it provides the atmosphere with ___oxygen________

and gives glucose to other orgamisms.

This makes __autotrophs____producers that give energy to ___consumers____.

Which of the following situations or phrases most accurately describes the citric acid cycle?

Bond [772]

The correct answer is: B) "All roads lead to Rome"

Citric acid cycle also called tricarboxylic acid (TCA) cycle and Krebs cycle is a central process in cellular respiration. Citric acid cycle that connects carbohydrate, fat, and protein metabolism so “all the roads” from the different metabolic pathways come to this cycle.

Acetyl-CoA which is produced through the oxidation of pyruvate (pyruvate is a product of glycolysis) enters the cycle which then produces reduced electron carriers NADH, FAD2 and energy molecule ATP. These electron carriers will then pass their electrons into the electron transport chain and, through the process of oxidative phosphorylation, will produce more ATP.

Please also describe how actin-binding sites are made available for cross-bridging with myosin heads during contraction.

yaroslaw [1]

Answer: The calcium ion binds to troponin, and this slides the tropomyosin rods away from the binding sites.

Explanation:

Contraction and relaxation of muscle cells brings about movements of the body. The contractile myofilament called sarcomeres are bounded at each end by a dense stripe called the Z - line, to which the myosin fibres are attached, and lying in the middle of the sarcomere are the actin filaments, overlapping with the myosin.

When action potential spreads from the nerve along the sarcolemma (muscle cell membrane), it penetrates deep into the muscle cell through the sarcoplasm (cytoplasm of muscle cell), and releases CALCIUM from the intracellular stores.CALCIUM triggers the binding of myosin to the actin filament next to it forming CROSS BRIDGES.

For this to occur, ACTIN BINDING SITE has to be made available. TROPOMYOSIN is a protein that winds around the chains of the actin filament and covers the myosin-binding sites to prevent actin from binding to myosin. The first step in the process of contraction is for calcium ions to bind to troponin so that tropomyosin can slide away from the binding sites on the actin strands.
