The R group should have the ability to form hydrogen bonds.
The R-group take a lot of different chemical forms and can
be acidic, basic, polar or non polar. Amino acids that are either acidic or basic
consequently have either positive or negative charge. These types of R-groups
are stabilized when surrounded by water.
A sperm cell and an egg cell fuse to form which structure?
zygote
zygote = a diploid cell resulting from the fusion of two haploid gametes; a fertilized ovum
NOT FETUS
confirmation bias?
i think that may be correct but i'm not 100% positive i hope it helps a little. Good Luck

Answer:
D. some components of the cycle are used as building blocks for certain anabolic pathways
Explanation:
Kreb's cycle starts when pyruvate enters the cycle in the form of acetyl CoA. The cycle completely breakdown acetyl CoA into CO2 and H2O. The released energy is stored in the form of NADH and FADH2 which enter oxidative phosphorylation to drive ATP synthesis. Kreb's cycle is an amphibolic pathway as it is involved in both catabolic and anabolic processes.
Some of the intermediates of Kreb's cycle serve as precursors for other anabolic pathways. For example, alpha-Ketoglutarate and oxaloacetate from Kreb's cycle enter the anabolic processes of synthesis of amino acids aspartate and glutamate respectively. Succinyl CoA from Kreb's cycle serves as one of the intermediates for the synthesis of porphyrin rings present in "heme" groups. The heme group is a structural and functional part of hemoglobin and myoglobin proteins.
